+    <title>Example</title>
+      <p>The following example demonstrates the basic functionality used to
+      run the Erlang ASN.1 compiler.</p>
+      <p>Create a file named <c>People.asn</c> containing the following:</p>
+      <pre>
+People DEFINITIONS AUTOMATIC TAGS ::=
+BEGIN
+  Person ::= SEQUENCE {
+    name PrintableString,
+    location INTEGER {home(0),field(1),roving(2)},
+    age INTEGER OPTIONAL
+  }
+END      </pre>
+      <p>This file must be compiled before it can be used.
+        The ASN.1 compiler checks that the syntax is correct and that the
+        text represents proper ASN.1 code before generating an abstract
+        syntax tree. The code-generator then uses the abstract syntax
+        tree to generate code.</p>
+      <p>The generated Erlang files are placed in the current directory or
+        in the directory specified with option <c>{outdir,Dir}</c>.</p>
+      <p>The following shows how the compiler
+        can be called from the  Erlang shell:</p>
+
+      <pre>
+1><input> asn1ct:compile("People", [ber]).</input>
+ok
+2>      </pre>
+
+      <p>Option <c>verbose</c> can be added to get information
+      about the generated files:</p>
+      <pre>
+2><input> asn1ct:compile("People", [ber,verbose]).</input>
+Erlang ASN.1 compiling "People.asn" 
+--{generated,"People.asn1db"}--
+--{generated,"People.hrl"}--
+--{generated,"People.erl"}--
+ok
+3>      </pre>
+
+      <p>ASN.1 module <c>People</c> is now accepted and the
+      abstract syntax tree is saved in file <c>People.asn1db</c>.
+      The generated Erlang code is compiled using the Erlang compiler
+      and loaded into the Erlang runtime system. There is now an API
+      for <c>encode/2</c> and <c>decode/2</c> in module
+      <c>People</c>, which is called like:<br></br>
+      <c><![CDATA['People':encode(<Type name>, <Value>)]]></c>
+      <br></br>
+        or<br></br>
+<c><![CDATA['People':decode(<Type name>, <Value>)]]></c></p>
+
+      <p>Assume that there is a network
+        application that receives instances of the ASN.1 defined
+        type <c>Person</c>, modifies, and sends them back again:</p>
+
+      <code type="none">
+receive
+   {Port,{data,Bytes}} ->
+       case 'People':decode('Person',Bytes) of
+           {ok,P} ->
+               {ok,Answer} = 'People':encode('Person',mk_answer(P)),
+               Port ! {self(),{command,Answer}};
+           {error,Reason} ->
+               exit({error,Reason})
+       end
+    end,      </code>
+      <p>In this example, a series of bytes is received from an
+        external source and the bytes are then decoded into a valid
+        Erlang term. This was achieved with the call
+        <c>'People':decode('Person',Bytes)</c>, which returned
+        an Erlang value of the ASN.1 type <c>Person</c>. Then an answer was
+        constructed  and encoded using
+        <c>'People':encode('Person',Answer)</c>, which takes an
+        instance of a defined ASN.1 type and transforms it to a
+        binary according to the BER or PER encoding rules.</p>
+        <p>The encoder and decoder can also be run from the shell:</p>
+      <pre>
+2> <input>Rockstar = {'Person',"Some Name",roving,50}.</input>
+{'Person',"Some Name",roving,50}
+3> <input>{ok,Bin} = 'People':encode('Person',Rockstar).</input>
+{ok,&lt;&lt;243,17,19,9,83,111,109,101,32,78,97,109,101,2,1,2,
+      2,1,50&gt;&gt;}
+4> <input>{ok,Person} = 'People':decode('Person',Bin).</input>
+{ok,{'Person',"Some Name",roving,50}}
+5>      </pre>

+      <title>Module Dependencies</title>
+      <p>It is common that ASN.1 modules import defined types, values, and
+        other entities from another ASN.1 module.</p>
+      <p>Earlier versions of the ASN.1 compiler required that modules
+        that were imported from had to be compiled before the module
+        that imported. This caused problems when ASN.1 modules had circular
+        dependencies.</p>
+      <p>Referenced modules are now parsed when the compiler finds an
+        entity that is imported. No code is generated for
+        the referenced module. However, the compiled modules rely on
+        that the referenced modules are also compiled.</p>
+    </section>

+    <title>ASN.1 Application User Interface</title>
+    <p>The <c>ASN.1</c> application provides the following two
+    separate user interfaces:</p>
+    <list type="bulleted">
+      <item>
+        <p>The module <c>asn1ct</c>, which provides the compile-time functions
+          (including the compiler)</p>
+      </item>
+      <item>
+        <p>The module <c>asn1rt_nif</c>, which provides the runtime functions
+         for the ASN.1 decoder for the BER back end</p>
+      </item>
+    </list>
+    <p>The reason for this division of the interfaces into compile-time
+      and runtime
+      is that only runtime modules (<c>asn1rt*</c>) need to be loaded in
+      an embedded system. 
+      </p>
+
+    <section>
+      <title>Compile-Time Functions</title>
+      <p>The ASN.1 compiler can be started directly from the command line
+        by the <c>erlc</c> program. This is convenient when compiling
+        many ASN.1 files from the command line or when using Makefiles.
+        Some examples of how the <c>erlc</c> command can be used to start
+        the ASN.1 compiler:</p>
+      <pre>
+erlc Person.asn
+erlc -bper Person.asn
+erlc -bber ../Example.asn
+erlc -o ../asnfiles -I ../asnfiles -I /usr/local/standards/asn1 Person.asn</pre>
+      <p>Useful options for the ASN.1 compiler:</p>
+      <taglist>
+        <tag><c>-b[ber | per | uper]</c></tag>
+        <item>
+          <p>Choice of encoding rules. If omitted, <c>ber</c> is the
+          default.</p>
+        </item>
+        <tag><c>-o OutDirectory</c></tag>
+        <item>
+          <p>Where to put the generated files. Default is the current
+            directory.</p>
+        </item>
+        <tag><c>-I IncludeDir</c></tag>
+        <item>
+          <p>Where to search for <c>.asn1db</c> files and ASN.1
+            source specs to resolve references to other
+            modules. This option can be repeated many times if there
+            are several places to search in. The compiler
+            searches the current directory first.</p>
+        </item>
+        <tag><c>+der</c></tag>
+        <item>
+          <p>DER encoding rule. Only when using option <c>-ber</c>.</p>
+        </item>
+        <tag><c>+asn1config</c></tag>
+        <item>
+          <p>This functionality works together with option
+            <c>ber</c>. It enables the specialized decodes, see Section
+            <seealso marker="asn1_spec">Specialized Decode</seealso>.</p>
+        </item>
+        <tag><c>+undec_rest</c></tag>
+        <item>
+          <p>A buffer that holds a message being decoded can also have
+          trailing bytes. If those trailing bytes are important, they
+          can be returned along with the decoded value by compiling
+          the ASN.1 specification with option <c>+undec_rest</c>.
+          The return value from the decoder is
+          <c>{ok,Value,Rest}</c> where <c>Rest</c> is a binary
+          containing the trailing bytes.</p>
+        </item>
+        <tag><c>+'Any Erlc Option'</c></tag>
+        <item>
+          <p>Any option can be added to the Erlang compiler when
+            compiling the generated Erlang files. Any option
+            unrecognized by the ASN.1 compiler is passed to the
+            Erlang compiler.</p>
+        </item>
+      </taglist>
+      <p>For a complete description of <c>erlc</c>, see
+        ERTS Reference Manual.</p>
+      <p>The compiler and other compile-time functions can also be started
+        from the Erlang shell. Here follows a brief
+        description of the primary functions. For a
+        complete description of each function, see module <c>asn1ct</c> in
+        the <seealso marker="asn1ct">ASN.1 Reference Manual</seealso>.</p>
+      <p>The compiler is started by <c>asn1ct:compile/1</c> with
+        default options, or <c>asn1ct:compile/2</c> if explicit options
+        are given.</p>
+      <p>Example:</p>
+      <pre>
+asn1ct:compile("H323-MESSAGES.asn1").      </pre>
+      <p>This equals:</p>
+      <pre>
+asn1ct:compile("H323-MESSAGES.asn1",[ber]).      </pre>
+      <p>If PER encoding is wanted:</p>
+      <pre>
+asn1ct:compile("H323-MESSAGES.asn1",[per]).      </pre>
+      <p>The generic encode and decode functions can be called
+      as follows:</p>
+      <pre>
+'H323-MESSAGES':encode('SomeChoiceType',{call,&lt;&lt;"octetstring"&gt;&gt;}).
+'H323-MESSAGES':decode('SomeChoiceType',Bytes).      </pre>

+      <title>Runtime Functions</title>
+      <p>When an ASN.1 specification is compiled with option <c>ber</c>,
+      the <c>asn1rt_nif</c> module and the NIF library in
+      <c>asn1/priv_dir</c> are needed at runtime.</p>
+      <p>By calling function <c>info/0</c> in a generated module, you
+      get information about which compiler options were used.</p>
+    </section>
+
+    <section>
+      <title>Errors</title>
+      <p>Errors detected at
+        compile-time are displayed on the screen together with line
+        numbers indicating where in the source file the respective error
+        was detected. If no errors are found, an Erlang ASN.1 module is
+        created.</p>
+      <p>The runtime encoders and decoders execute within a catch and
+      return <c>{ok, Data}</c> or
+        <c>{error, {asn1, Description}}</c> where
+        <c>Description</c> is
+        an Erlang term describing the error.</p>

+    <title>Multi-File Compilation</title>
+    <p>There are various reasons for using multi-file compilation:</p>
+    <list type="bulleted">
+      <item>To choose the name for the generated module, for
+      example, because you need to compile the same specs for
+      different encoding rules.</item>
+      <item>You want only one resulting module.</item>
+    </list>
+    <p>Specify which ASN.1 specs to compile in a module with extension
+      <c>.set.asn</c>. Choose a module name and provide the
+      names of the ASN.1 specs. For example, if you have the specs
+      <c>File1.asn</c>, <c>File2.asn</c>, and <c>File3.asn</c>, your
+      module <c>MyModule.set.asn</c> looks as follows:</p>
+    <pre>
+File1.asn
+File2.asn
+File3.asn    </pre>
+    <p>If you compile with the following, the result is one merged
+    module <c>MyModule.erl</c> with the generated code from the three
+    ASN.1 specs:</p>
+    <code type="none">
+~> erlc MyModule.set.asn    </code>
+  </section>
+
+  <section>
+    <title>Remark about Tags</title>
+
+    <p>Tags used to be important for all users of ASN.1, because it
+    was necessary to add tags manually to certain constructs in order
+    for the ASN.1 specification to be valid. Example of
+    an old-style specification:</p>
+
+    <pre>
+Tags DEFINITIONS ::=
+BEGIN
+  Afters ::= CHOICE { cheese [0] IA5String,
+                      dessert [1] IA5String }
+END </pre>
+
+    <p>Without the tags (the numbers in square brackets) the ASN.1
+    compiler refused to compile the file.</p>
+
+    <p>In 1994 the global tagging mode <c>AUTOMATIC TAGS</c> was introduced.
+    By putting <c>AUTOMATIC TAGS</c> in the module header, the ASN.1
+    compiler automatically adds tags when needed. The following is the
+    same specification in <c>AUTOMATIC TAGS</c> mode:</p>
+
+    <pre>
+Tags DEFINITIONS AUTOMATIC TAGS ::=
+BEGIN
+  Afters ::= CHOICE { cheese IA5String,
+                      dessert IA5String }
+END </pre>
+
+    <p>Tags are not mentioned any more in this User's Guide.</p>

+      <p>The values of each ASN.1 type have their own representation in Erlang, as
+        described in the following sections. Users must provide
+        these values for encoding according to the representation, as shown in the
+        following example:</p>
+    </note>
+    <pre>
+Operational ::= BOOLEAN --ASN.1 definition    </pre>
+    <p>In Erlang code it can look as follows:</p>

+
+    <section>
+      <marker id="BOOLEAN"></marker>
+      <title>BOOLEAN</title>
+      <p>Booleans in ASN.1 express values that can be either
+        <c>TRUE</c> or <c>FALSE</c>.
+        The meanings assigned to <c>TRUE</c> and <c>FALSE</c> are outside the scope

+      <pre>
+Operational ::= BOOLEAN</pre>
+      <p>Assigning a value to type <c>Operational</c> in Erlang is possible by
+        using the following Erlang code:</p>
+      <code type="erl">
+Myvar1 = true,</code>
+      <p>Thus, in Erlang the atoms <c>true</c> and <c>false</c> are used

+      <title>INTEGER</title>
+      <p>ASN.1 itself specifies indefinitely large integers. Erlang

+      <p>The concept of subtyping can be applied to integers and

+T3 ::= INTEGER (0..MAX)
+T4 ::= INTEGER (0&lt;..MAX)
+T5 ::= INTEGER (MIN&lt;..-99)

+Day1 = saturday,</pre>
+      <p>The enumerated type is similar to an integer type, when

+      <title>OCTET STRING</title>
+      <p><c>OCTET STRING</c> is the simplest of all ASN.1 types. <c>OCTET
+      STRING</c> only moves or transfers, for example, binary files or other
+      unstructured information complying with two rules: the
+      bytes consist of octets and encoding is not required.</p>
+      <p>It is possible to have the following ASN.1 type definitions:</p>
+      <pre>
+O1 ::= OCTET STRING
+O2 ::= OCTET STRING (SIZE(28))      </pre>
+      <p>With the following example assignments in Erlang:</p>

+O1Val = &lt;&lt;17,13,19,20,0,0,255,254&gt;&gt;,
+O2Val = &lt;&lt;"must be exactly 28 chars...."&gt;&gt;,</pre>
+       <p>By default, an <c>OCTET STRING</c> is always represented as

+       option <c>legacy_erlang_types</c>, the encode functions
+       accept both lists and binaries, and the decode functions
+       decode an <c>OCTET STRING</c> to a list.</p>

+      <marker id="Character Strings"></marker>
+      <title>Character Strings</title>
+      <p>ASN.1 supports a wide variety of character sets. The main difference
+        between an <c>OCTET STRING</c> and a character string is that the
+        <c>OCTET STRING</c> has no imposed semantics on the bytes delivered.</p>
+      <p>However, when using, for example, IA5String (which closely
+        resembles ASCII), byte 65 (in decimal
+        notation) <em>means</em> character 'A'.
+        </p>
+      <p>For example, if a defined type is to be a VideotexString and
+        an octet is received with the unsigned integer value <c>X</c>,
+        the octet is to be interpreted as specified in standard
+        ITU-T T.100, T.101. 
+        </p>
+      <p>The  ASN.1 to Erlang compiler
+        does not determine the correct interpretation of each BER
+        string octet value with different character strings. The
+        application is responsible for interpretation
+        of octets. Therefore, from the BER
+        string point of view, octets are very similar to
+        character strings and are compiled in the same way.
+        </p>
+      <p>When PER is
+        used, there is a significant difference in the encoding scheme
+        between <c>OCTET STRING</c>s and other strings. The constraints
+        specified for a type are especially important for PER, where
+        they affect the encoding.
+        </p>
+      <p>Examples:</p>
+      <pre>
+Digs ::= NumericString (SIZE(1..3))
+TextFile ::= IA5String (SIZE(0..64000))      </pre>
+      <p>The corresponding Erlang assignments:</p>
+      <pre>
+DigsVal1 = "456",
+DigsVal2 = "123",
+TextFileVal1 = "abc...xyz...",
+TextFileVal2 = [88,76,55,44,99,121 .......... a lot of characters here ....]</pre>
+      <p>The Erlang representation for "BMPString" and
+        "UniversalString" is either a list of ASCII values or a list
+        of quadruples. The quadruple representation associates to the
+        Unicode standard representation of characters. The ASCII
+        characters are all represented by quadruples beginning with
+        three zeros like {0,0,0,65} for character 'A'. When
+        decoding a value for these strings, the result is a list of
+        quadruples, or integers when the value is an ASCII character.</p>

+      <title>SEQUENCE</title>
+      <p>The structured types of ASN.1 are constructed from other types
+        in a manner similar to the concepts of array and struct in  C.</p>
+      <p>A <c>SEQUENCE</c> in ASN.1 is
+        comparable with a struct in C and a record in Erlang.
+        A <c>SEQUENCE</c> can be defined as follows:</p>
+      <pre>
+Pdu ::= SEQUENCE {
+   a INTEGER,
+   b REAL,
+   c OBJECT IDENTIFIER,
+   d NULL }      </pre>
+      <p>This is a 4-component structure called <c>Pdu</c>. The record format
+        is the major format for representation of <c>SEQUENCE</c> in Erlang.
+        For each <c>SEQUENCE</c> and <c>SET</c> in an ASN.1 module an Erlang
+        record declaration is generated. For <c>Pdu</c>, a record
+        like the following is defined:</p>
+      <pre>
+-record('Pdu',{a, b, c, d}).      </pre>
+      <p>The record declarations for a module <c>M</c> are placed in a
+        separate <c>M.hrl</c> file.</p>
+      <p>Values can be assigned in Erlang as follows:</p>
+      <pre>
+MyPdu = #'Pdu'{a=22,b=77.99,c={0,1,2,3,4},d='NULL'}.      </pre>
+      <p>The decode functions return a record as result when decoding
+      a <c>SEQUENCE</c> or a <c>SET</c>.</p>
+
+      <p>A <c>SEQUENCE</c> and a <c>SET</c> can contain a component
+      with a <c>DEFAULT</c> keyword followed by the actual value, which
+      is the default value. The <c>DEFAULT</c> keyword means that the
+      application doing the encoding can omit encoding of the value, which
+      results in fewer bytes to send to the receiving application.</p>
+
+      <p>An application can use the atom <c>asn1_DEFAULT</c> to indicate
+      that the encoding is to be omitted for that position in
+      the <c>SEQUENCE</c>.</p>
+
+      <p>Depending on the encoding rules, the encoder can also compare
+      the given value to the default value and automatically omit the
+      encoding if the values are equal. How much effort the encoder makes
+      to compare the values depends on the encoding rules. The DER
+      encoding rules forbid encoding a value equal to the default value,
+      so it has a more thorough and time-consuming comparison than the
+      encoders for the other encoding rules.</p>

+      <p>The type <c>CHOICE</c> is a space saver and is similar to the

+SomeModuleName DEFINITIONS AUTOMATIC TAGS ::=
+BEGIN
+T ::= CHOICE {
+        x REAL,
+        y INTEGER,
+        z OBJECT IDENTIFIER }
+END </pre>
+      <p>It is then possible to assign values as follows:</p>
+      <pre>
+TVal1 = {y,17},
+TVal2 = {z,{0,1,2}},</pre>
+      <p>A <c>CHOICE</c> value is always represented as the tuple
+        <c>{ChoiceAlternative, Val}</c> where <c>ChoiceAlternative</c>
+        is an atom denoting the selected choice alternative.

+        <title>Extensible CHOICE</title>
+        <p>When a <c>CHOICE</c> contains an extension marker and the
+         decoder detects an unknown alternative of the <c>CHOICE</c>,
+         the value is represented as follows:</p>
+        <pre>
+{asn1_ExtAlt, BytesForOpenType}</pre>
+        <p>Here <c>BytesForOpenType</c> is a list of bytes constituting the

+      <title>SET OF and SEQUENCE OF</title>
+      <p>The types <c>SET OF</c> and <c>SEQUENCE OF</c> correspond
+        to the concept of an array
+        in several programming languages. The Erlang syntax for
+        both types is straightforward, for example:</p>
+      <pre>
+Arr1 ::= SET SIZE (5) OF INTEGER (4..9) 
+Arr2 ::= SEQUENCE OF OCTET STRING      </pre>
+      <p>In Erlang the following can apply:</p>
+      <pre>
+Arr1Val = [4,5,6,7,8],
+Arr2Val = ["abc",[14,34,54],"Octets"],      </pre>
+      <p>Notice that the definition of type <c>SET OF</c> implies that
+        the order of the components is undefined, but in practice there is 
+        no difference between <c>SET OF</c> and <c>SEQUENCE OF</c>.
+        The ASN.1 compiler for Erlang does not randomize the order of the
+        <c>SET OF</c> components before encoding.</p>
+      <p>However, for a value of type <c>SET OF</c>, the DER
+        encoding format requires the elements to be sent in ascending
+        order of their encoding, which implies an expensive sorting
+        procedure in runtime. Therefore it is recommended to
+        use <c>SEQUENCE OF</c> instead of <c>SET OF</c> if possible.</p>

+      <title>ANY and ANY DEFINED BY</title>
+      <p>The types <c>ANY</c> and <c>ANY DEFINED BY</c> have been removed
+        from the standard since 1994. It is recommended not to use
+        these types any more. They can, however, exist in some old ASN.1
+        modules. The idea with this type was to leave a "hole" in a 
+        definition where it was possible to
+        put unspecified data of any kind, even non-ASN.1 data.</p>
+      <p>A value of this type is encoded as an <c>open type</c>.</p>
+      <p>Instead of <c>ANY</c> and <c>ANY DEFINED BY</c>, it is
+        recommended to use
+        <c>information object class</c>, <c>table constraints</c>, and
+        <c>parameterization</c>. In particular the construct
+        <c>TYPE-IDENTIFIER.@Type</c> accomplish the same as the
+        deprecated <c>ANY</c>.</p>

+      <p>The types <c>EXTERNAL</c>, <c>EMBEDDED PDV</c>, and
+      <c>CHARACTER STRING</c> are used in presentation layer negotiation.
+        They are encoded according to their associated type, see X.680.</p>
+      <p>The type <c>EXTERNAL</c> had a slightly different associated type
+        before 1994. X.691 states that encoding must follow
+        the older associated type. So, generated encode/decode
+        functions convert values of the newer format to the older format
+        before encoding. This implies that it is allowed to use
+        <c>EXTERNAL</c> type values of either format for encoding. Decoded
+        values are always returned in the newer format.</p>

+      <title>Embedded Named Types</title>
+      <p>The structured types previously described can have other named
+        types as their components. The general syntax to assign a value
+        to component <c>C</c> of a named ASN.1 type <c>T</c> in Erlang
+        is the record syntax <c>#'T'{'C'=Value}</c>.
+        Here <c>Value</c> can be a value of yet another type <c>T2</c>,
+        for example:</p>
+      <pre>
+EmbeddedExample DEFINITIONS AUTOMATIC TAGS ::=
+BEGIN
+B ::= SEQUENCE {
+        a Arr1,
+        b T }
+

+T ::= CHOICE {
+        x REAL,
+        y INTEGER,
+        z OBJECT IDENTIFIER }
+        END      </pre>
+      <p><c>SEQUENCE</c> <c>b</c> can be encoded as follows in Erlang:</p>
+      <pre>
+1> 'EmbeddedExample':encode('B', {'B',[4,5,6,7,8],{x,"7.77"}}).

+    <title>Naming of Records in .hrl Files</title>
+    <p>When an ASN.1 specification is compiled, all defined types of type
+      <c>SET</c> or <c>SEQUENCE</c> result in a corresponding record in the
+      generated <c>.hrl</c> file. This is because the values for
+      <c>SET</c> and <c>SEQUENCE</c> are represented as records as
+      mentioned earlier.</p>
+    <p>Some special cases of this functionality are presented in the
+      next section.</p>
+
+    <section>
+      <title>Embedded Structured Types</title>
+      <p>In ASN.1 it is also possible to have components that are themselves
+        structured types.
+        For example, it is possible to have the following:</p>
+      <pre>
+Emb ::= SEQUENCE {
+    a SEQUENCE OF OCTET STRING,
+    b SET {
+       a INTEGER,
+       b INTEGER DEFAULT 66},
+    c CHOICE {
+       a INTEGER,
+       b FooType } }
+
+FooType ::= [3] VisibleString      </pre>
+      <p>The following records are generated because of type <c>Emb</c>:</p>
+      <pre>
+-record('Emb,{a, b, c}).
+-record('Emb_b',{a, b = asn1_DEFAULT}). % the embedded SET type </pre>
+      <p>Values of type <c>Emb</c> can be assigned as follows:</p>
+      <code type="none">
+V = #'Emb'{a=["qqqq",[1,2,255]], 
+           b = #'Emb_b'{a=99}, 
+           c ={b,"Can you see this"}}.</code>
+      <p>For an embedded type of type <c>SEQUENCE</c>/<c>SET</c> in a
+        <c>SEQUENCE</c>/<c>SET</c>, the record name is extended with an
+        underscore and the component name. If the embedded structure is
+        deeper with the <c>SEQUENCE</c>, <c>SET</c>, or <c>CHOICE</c>
+        types in the line, each component name/alternative name is
+        added to the record name.</p>
+      <p>Example:</p>
+      <pre>
+Seq ::= SEQUENCE{
+    a CHOICE{
+        b SEQUENCE {
+           c  INTEGER
+        }
+    }
+}      </pre>
+      <p>This results in the following record:</p>
+      <pre>
+-record('Seq_a_b',{c}).      </pre>
+      <p>If the structured type has a component with an embedded
+        <c>SEQUENCE OF</c>/<c>SET OF</c> which embedded type in turn
+        is a <c>SEQUENCE</c>/<c>SET</c>, it gives a record with the
+        <c>SEQUENCE OF</c>/<c>SET OF</c>
+        addition as in the following example:</p>
+      <pre>
+Seq ::= SEQUENCE {
+    a SEQUENCE OF SEQUENCE {
+           b
+               }
+    c SET OF SEQUENCE {
+           d
+               }
+}      </pre>
+      <p>This results in the following records:</p>
+      <pre>
+-record('Seq_a_SEQOF'{b}).
+-record('Seq_c_SETOF'{d}).      </pre>
+      <p>A parameterized type is to be considered as an embedded
+        type. Each time such a type is referenced, an instance of it is
+        defined. Thus, in the following example a record with name
+        <c>'Seq_b'</c> is generated in the <c>.hrl</c> file and is used
+        to hold values:</p>
+      <pre>
+Seq ::= SEQUENCE {
+    b PType{INTEGER}
+}
+
+PType{T} ::= SEQUENCE{
+    id T
+}      </pre>
+    </section>
+
+    <section>
+      <title>Recursive Types</title>
+      <p>Types that refer to themselves are called recursive types.
+      Example:</p>
+      <pre>
+Rec ::= CHOICE {
+     nothing NULL,
+     something SEQUENCE {
+          a INTEGER,
+          b OCTET STRING,
+          c Rec }}      </pre>
+      <p>This is allowed in ASN.1 and the ASN.1-to-Erlang compiler
+      supports this recursive type.
+      A value for this type is assigned in Erlang as follows:</p>
+      <pre>
+V = {something,#'Rec_something'{a = 77, 
+                                b = "some octets here", 
+                                c = {nothing,'NULL'}}}.      </pre>
+    </section>
+  </section>
+
+  <section>
+    <title>ASN.1 Values</title>
+    <p>Values can be assigned to an ASN.1 type within the ASN.1 code
+      itself, as opposed to the actions in the previous section where
+      a value was assigned to an ASN.1 type in Erlang. The full value
+      syntax of ASN.1 is supported and X.680 describes in detail how
+      to assign values in ASN.1. A short example:</p>
+    <pre>
+TT ::= SEQUENCE {
+   a INTEGER,
+   b SET OF OCTET STRING }
+
+tt TT ::= {a 77,b {"kalle","kula"}}    </pre>
+    <p>The value defined here can be used in several ways. It can, for
+      example, be used as the value in some <c>DEFAULT</c> component:</p>
+    <pre>
+SS ::= SET {
+    s OBJECT IDENTIFIER,
+    val TT DEFAULT tt }    </pre>
+    <p>It can also be used from inside an Erlang program. If this ASN.1
+      code is defined in ASN.1 module <c>Values</c>, the ASN.1 value
+      <c>tt</c> can be reached from Erlang as a function call to
+      <c>'Values':tt()</c> as in the following example:</p>
+    <pre>
+1> <input>Val = 'Values':tt().</input>
+{'TT',77,["kalle","kula"]}
+2> <input>{ok,Bytes} = 'Values':encode('TT',Val).</input>
+{ok,&lt;&lt;48,18,128,1,77,161,13,4,5,107,97,108,108,101,4,4,
+      107,117,108,97&gt;&gt;}
+4> <input>'Values':decode('TT',Bytes).</input>
+{ok,{'TT',77,["kalle","kula"]}}
+5>  </pre>
+    <p>This example shows that a function is generated by the compiler
+      that returns a valid Erlang representation of the value, although
+      the value is of a complex type.</p>
+    <p>Furthermore, a macro is generated for each value in the <c>.hrl</c>
+      file. So, the defined value <c>tt</c> can also be extracted by
+      <c>?tt</c> in application code.</p>
+  </section>
+
+  <section>
+    <title>Macros</title>
+    <p>The type <c>MACRO</c> is not supported. It is no longer part of
+    the ASN.1 standard.</p>

+    <marker id="Information Object"></marker>
+    <title>ASN.1 Information Objects (X.681)</title>
+    <p>Information Object Classes, Information Objects, and Information
+      Object Sets (in the following called classes, objects, and
+      object sets, respectively) are defined in the standard
+      definition X.681. Only a brief explanation is given here.</p>
+    <p>These constructs makes it possible to define open types, that
+      is, values of that type can be of any ASN.1 type. Also,
+      relationships can be defined between different types and
+      values, as classes can hold types, values, objects, object
+      sets, and other classes in their fields. A class can be
+      defined in ASN.1 as follows:</p>
+    <pre>
+GENERAL-PROCEDURE ::= CLASS {
+      &amp;Message,
+      &amp;Reply               OPTIONAL,
+      &amp;Error               OPTIONAL,
+      &amp;id          PrintableString UNIQUE
+}
+WITH SYNTAX {
+      NEW MESSAGE     &amp;Message
+      [REPLY           &amp;Reply]
+      [ERROR           &amp;Error]
+      ADDRESS          &amp;id
+}    </pre>
+    <p>An object is an instance of a class. An object set is a set
+      containing objects of a specified class. A definition can look
+      as follows:</p>
+    <pre>
+object1 GENERAL-PROCEDURE ::= {
+    NEW MESSAGE      PrintableString
+    ADDRESS          "home"
+}
+
+object2 GENERAL-PROCEDURE ::= {
+    NEW MESSAGE INTEGER
+    ERROR INTEGER
+    ADDRESS "remote"
+}</pre>
+    <p>The object <c>object1</c> is an instance of the class
+      <c>GENERAL-PROCEDURE</c> and has one type field and one
+      fixed type value field. The object <c>object2</c> has also an
+      optional field <c>ERROR</c>, which is a type field. The field
+      <c>ADDRESS</c> is a <c>UNIQUE</c> field. Objects in an object set
+      must have unique values in their <c>UNIQUE</c> field, as in
+      <c>GENERAL-PROCEDURES</c>:</p>
+    <pre>
+GENERAL-PROCEDURES GENERAL-PROCEDURE ::= {
+    object1 | object2}    </pre>
+    <p>You cannot encode a class, object, or object set, only refer to
+      it when defining other ASN.1 entities. Typically you refer to a
+      class as well as to object sets by table constraints and component
+      relation constraints (X.682) in ASN.1 types, as in the following:</p>
+    <pre>
+StartMessage  ::= SEQUENCE {
+    msgId  GENERAL-PROCEDURE.&amp;id  ({GENERAL-PROCEDURES}),
+    content GENERAL-PROCEDURE.&amp;Message ({GENERAL-PROCEDURES}{@msgId}),
+    }    </pre>
+    <p>In type <c>StartMessage</c>, the constraint following field
+      <c>content</c> tells that in a value of type
+      <c>StartMessage</c> the value in field <c>content</c> must
+      come from the same object that is chosen by field <c>msgId</c>.</p>
+    <p>So, the value
+      <c>#'StartMessage'{msgId="home",content="Any Printable String"}</c>
+      is legal to encode as a <c>StartMessage</c> value. However, the value
+      <c>#'StartMessage'{msgId="remote", content="Some String"}</c>
+      is illegal as the constraint in <c>StartMessage</c> tells that
+      when you have chosen a value from a specific object in object
+      set <c>GENERAL-PROCEDURES</c> in field 
+      <c>msgId</c>, you must choose a value from that same object in
+      the content field too. In this second case, it is to be
+      any <c>INTEGER</c> value.</p>
+    <p><c>StartMessage</c> can in field <c>content</c> be
+      encoded with a value of any type that an object in object set
+      <c>GENERAL-PROCEDURES</c> has in its <c>NEW MESSAGE</c> field.
+      This field refers to a type field
+      <c>&amp;Message</c> in the class. Field <c>msgId</c> is always
+      encoded as a <c>PrintableString</c>, as the field refers to a
+      fixed type in the class.</p>
+    <p>In practice, object sets are usually declared to be extensible so
+      that more objects can be added to the set later. Extensibility is
+      indicated as follows:</p>
+    <pre>
+GENERAL-PROCEDURES GENERAL-PROCEDURE ::= {
+    object1 | object2, ...}    </pre>
+     <p>When decoding a type that uses an extensible set constraint,
+     it is always possible that the value in field <c>UNIQUE</c>
+     is unknown (that is, the type has been encoded with a later
+     version of the ASN.1 specification). The unencoded data is then
+     returned wrapped in a tuple as follows:</p>
+
+     <pre>
+{asn1_OPENTYPE,Binary}</pre>
+
+     <p>Here <c>Binary</c> is an Erlang binary that contains the encoded
+     data. (If option <c>legacy_erlang_types</c> has been given,
+     only the binary is returned.)</p>
+  </section>
+
+  <section>
+    <title>Parameterization (X.683)</title>
+    <p>Parameterization, which is defined in X.683, can be used when
+      defining types, values, value sets, classes, objects, or object sets.
+      A part of a definition can be supplied as a parameter. For
+      example, if a <c>Type</c> is used in a definition with a certain
+      purpose, you want the type name to express the intention. This
+      can be done with parameterization.</p>
+    <p>When many types (or another ASN.1 entity) only differ in some
+      minor cases, but the structure of the types is similar, only
+      one general type can be defined and the differences can be supplied
+      through parameters.</p>
+    <p>Example of use of parameterization:</p>
+    <pre>
+General{Type} ::= SEQUENCE
+{
+     number     INTEGER,
+     string     Type
+}
+      
+T1 ::= General{PrintableString}
+
+T2 ::= General{BIT STRING}</pre>
+    <p>An example of a value that can be encoded as type <c>T1</c> is
+      <c>{12,"hello"}</c>.</p>
+    <p>Notice that the compiler does not generate encode/decode functions
+      for parameterized types, only for the instances of the parameterized
+      types. Therefore, if a file contains the types <c>General{}</c>,
+      <c>T1</c>, and <c>T2</c> as in the previous example, encode/decode
+      functions are only generated for <c>T1</c> and <c>T2</c>.

+  <title>Introduction</title>
+
+      <p>ASN.1 is a formal language for
+      describing data structures to be exchanged between distributed
+      computer systems. The purpose of ASN.1 is to have a platform
+      and programming language independent notation to express types
+      using a standardized set of rules for the transformation of
+      values of a defined type into a stream of bytes. This stream of
+      bytes can then be sent on any type of communication
+      channel. This way, two applications written in different
+      programming languages running on different computers, and with
+      different internal representation of data, can exchange instances
+      of structured data types.</p>

     <title>Exclusive Decode</title>
     <p>The basic idea with exclusive
-      decode is that you specify which parts of the message you want to
+      decode is to specify which parts of the message you want to
       exclude from being decoded. These parts remain encoded and are
-      returned in the value structure as binaries. They may be decoded
+      returned in the value structure as binaries. They can be decoded
       in turn by passing them to a certain <c>decode_part/2</c>
-      function. The performance gain is high when the message is large
-      and you can do an exclusive decode and later on one or several
-      decodes of the parts or a second complete decode instead of two or
+      function. The performance gain is high for large messages.
+      You can do an exclusive decode and later one or more
+      decodes of the parts, or a second complete decode instead of two or
       more complete decodes.
       </p>
 
     <section>
-      <title>How To Make It Work</title>
-      <p>In order to make exclusive decode work you have to do the

       <list type="bulleted">
-        <item>First,decide the name of the function for the exclusive

-         specification and a notation that tells which parts of the

-         instructions shall be included in a configuration
-         file. </item>
-        <item>Third, compile with the additional option
-        <c>asn1config</c>. The compiler searches for a configuration
-         file with the same name as the ASN.1 spec but with the

-         as used for compilation of a set of files. See section

       <title>User Interface</title>
-      <p>The run-time user interface for exclusive decode consists of

-        file. Second, the compiler generates a <c>decode_part/2</c>
-        function when exclusive decode is chosen. This function decodes
-        the parts that were left undecoded during the exclusive
-        decode. Both functions are described below.

-      <title>Overview</title>
-      <p>ASN.1 (Abstract Syntax Notation One) is a formal language for
-      describing data structures to be exchanged between distributed
-      computer systems. The purpose of ASN.1 is to have a platform
-      and programming language independent notation to express types
-      using a standardized set of rules for the transformation of
-      values of a defined type into a stream of bytes. This stream of
-      bytes can then be sent on any type of communication
-      channel. This way, two applications written in different
-      programming languages running on different computers with
-      different internal representation of data can exchange instances
-      of structured data types.</p>
-    </section>
-
-    <section>
-      <title>Prerequisites</title>
-      <p>It is assumed that the reader is familiar with the ASN.1
-      notation as documented in the standard definition [<cite
-      id="X.680"></cite>] which is the primary text. It may also be
-      helpful, but not necessary, to read the standard definitions
-      [<cite id="X.681"></cite>] [<cite id="X.682"></cite>] [<cite
-      id="X.683"></cite>] [<cite id="X.690"></cite>] [<cite
-      id="X.691"></cite>]. </p>
-      <p>A good book explaining those reference texts is
-        [<cite id="DUBUISSON"></cite>], which is free to download at
-        <url href="http://www.oss.com/asn1/dubuisson.html">http://www.oss.com/asn1/dubuisson.html</url>.

-      <title>Capabilities</title>
-      <p>This application covers all features of ASN.1 up to the 1997
-      edition of the specification. In the 2002 edition of ASN.1 a
-      number of new features were introduced.  The following features
-      of the 2002 edition are fully or partly supported as shown
-      below:</p>
-      <list type="bulleted">
-	<item>
-	  <p>Decimal notation (e.g., "1.5e3") for REAL values. The
-	  NR1, NR2 and NR3 formats as explained in ISO6093 are
-	  supported.</p>
-	</item>
-	<item>
-	  <p>The RELATIVE-OID type for relative object identifiers is
-	  fully supported.</p>
-	</item>
-	<item>
-	  <p>The subtype constraint (CONTAINING/ENCODED BY) to
-	  constrain the content of an octet string or a bit string is
-	  parsed when compiling, but no further action is taken. This
-	  constraint is not a PER-visible constraint.</p>
-	</item>
-	<item>
-	  <p>The subtype constraint by regular expressions (PATTERN)
-	  for character string types is parsed when compiling, but no
-	  further action is taken. This constraint is not a

-    <title>Getting Started with Asn1</title>
-
-    <section>
-      <title>A First Example</title>
-      <p>The following example demonstrates the basic functionality used to run 
-        the Erlang ASN.1 compiler.</p>
-      <p>Create a file called <c>People.asn</c> containing the following:</p>
-      <pre>
-People DEFINITIONS AUTOMATIC TAGS ::=
-BEGIN
-  Person ::= SEQUENCE {
-    name PrintableString,
-    location INTEGER {home(0),field(1),roving(2)},
-    age INTEGER OPTIONAL
-  }
-END      </pre>
-      <p>This file (<c>People.asn</c>) must be compiled before it can be
-        used. 
-        The ASN.1 compiler checks that the syntax is correct and that the 
-        text represents proper ASN.1 code before generating an abstract
-        syntax tree. The code-generator then uses the abstract syntax 
-        tree in order to generate code.
-        </p>
-      <p>The generated Erlang  files will be placed in the current directory or
-        in the directory specified with the <c>{outdir,Dir}</c> option.
-        The following shows how the compiler
-        can be called from the  Erlang shell:</p>
-      <pre>
-1><input> asn1ct:compile("People", [ber]).</input>
-ok
-2>      </pre>
-
-      <p>The <c>verbose</c> option can be given to have information
-      about the generated files printed:</p>
-      <pre>
-2><input> asn1ct:compile("People", [ber,verbose]).</input>
-Erlang ASN.1 compiling "People.asn" 
---{generated,"People.asn1db"}--
---{generated,"People.hrl"}--
---{generated,"People.erl"}--
-ok
-3>      </pre>
-
-      <p>The ASN.1 module <c>People</c> is now accepted and the
-      abstract syntax tree is saved in the <c>People.asn1db</c> file;
-      the generated Erlang code is compiled using the Erlang compiler
-      and loaded into the Erlang run-time system. Now there is an API
-      for <c>encode/2</c> and <c>decode/2</c> in the module
-      <c>People</c>, which is invoked by: <br></br>
-      <c><![CDATA['People':encode(<Type name>, <Value>)]]></c>
-      <br></br>
-        or        <br></br>
-<c><![CDATA['People':decode(<Type name>, <Value>)]]></c></p>
-
-      <p>Assume there is a network
-        application which receives instances of the  ASN.1 defined
-        type Person,  modifies and sends them back again:</p>
-      <code type="none">
-receive
-   {Port,{data,Bytes}} ->
-       case 'People':decode('Person',Bytes) of
-           {ok,P} ->
-               {ok,Answer} = 'People':encode('Person',mk_answer(P)),
-               Port ! {self(),{command,Answer}};
-           {error,Reason} ->
-               exit({error,Reason})
-       end
-    end,      </code>
-      <p>In the example above, a  series of bytes is received from an
-        external source and the bytes are then decoded into a valid
-        Erlang term. This was achieved with the call
-        <c>'People':decode('Person',Bytes)</c> which   returned
-        an Erlang value of the ASN.1 type <c>Person</c>.  Then an answer was
-        constructed  and encoded using
-        <c>'People':encode('Person',Answer)</c> which takes an
-        instance of a defined ASN.1 type and transforms it to a
-        binary according to the BER or PER encoding rules.
-                <br></br>
-The encoder and the decoder can also be run from
-        the shell.</p>
-      <pre>
-2> <input>Rockstar = {'Person',"Some Name",roving,50}.</input>
-{'Person',"Some Name",roving,50}
-3> <input>{ok,Bin} = 'People':encode('Person',Rockstar).</input>
-{ok,&lt;&lt;243,17,19,9,83,111,109,101,32,78,97,109,101,2,1,2,
-      2,1,50&gt;&gt;}
-4> <input>{ok,Person} = 'People':decode('Person',Bin).</input>
-{ok,{'Person',"Some Name",roving,50}}
-5>      </pre>

-      <title>Module dependencies</title>
-      <p>It is common that ASN.1 modules import defined types, values and
-        other entities from another ASN.1 module.</p>
-      <p>Earlier versions of the ASN.1 compiler required that modules that
-        were imported from had to be compiled before the module that
-        imported. This caused problems when ASN.1 modules had circular
-        dependencies.</p>
-      <p>Referenced modules are now parsed when the compiler finds an
-        entity that is imported. There will not be any code generated for
-        the referenced module. However, the compiled module rely on
-        that the referenced modules also will be compiled.</p>
-    </section>

-  <section>
-    <title>The Asn1 Application User Interface</title>
-    <p>The Asn1 application provides two separate user interfaces:</p>
-    <list type="bulleted">
-      <item>
-        <p>The module <c>asn1ct</c> which provides the compile-time functions 
-          (including the compiler).</p>
-      </item>
-      <item>
-        <p>The module <c>asn1rt_nif</c> which provides the run-time functions
-	for the ASN.1 decoder for the BER back-end.</p>
-      </item>
-    </list>
-    <p>The reason for the division  of the interface into  compile-time 
-      and  run-time 
-      is that only run-time modules (<c>asn1rt*</c>) need to be loaded in
-      an embedded system. 
-      </p>
-
-    <section>
-      <title>Compile-time Functions</title>
-      <p>The ASN.1 compiler can be invoked directly from the command-line
-        by means of the <c>erlc</c> program. This is convenient when compiling
-        many ASN.1 files from the command-line or when using Makefiles.
-        Here are some examples of how the <c>erlc</c> command can be used to invoke the
-        ASN.1 compiler:</p>
-      <pre>
-erlc Person.asn
-erlc -bper Person.asn
-erlc -bber ../Example.asn
-erlc -o ../asnfiles -I ../asnfiles -I /usr/local/standards/asn1 Person.asn      </pre>
-      <p>The useful options for the ASN.1 compiler are:</p>

-    <title>Multi-file Compilation</title>
-    <p>There are various reasons for using multi-file compilation:</p>
-    <list type="bulleted">
-      <item>You want to choose the name for the generated module,
-      perhaps because you need to compile the same specs for
-      different encoding rules.</item>
-      <item>You want only one resulting module.</item>
-    </list>
-    <p>You need to specify which ASN.1 specs you will
-      compile in a module that must have the extension
-      <c>.set.asn</c>. You chose name of the module and provide the
-      names of the ASN.1 specs. For instance, if you have the specs
-      <c>File1.asn</c>, <c>File2.asn</c> and <c>File3.asn</c> your
-      module <c>MyModule.set.asn</c> will look like:</p>
-    <pre>
-File1.asn
-File2.asn
-File3.asn    </pre>
-    <p>If you compile with:</p>
-    <code type="none">
-~> erlc MyModule.set.asn    </code>
-    <p>the result will be one merged module <c>MyModule.erl</c> with
-      the generated code from the three ASN.1 specs.

-    <title>A quick note about tags</title>
-
-    <p>Tags used to be important for all users of ASN.1, because it
-    was necessary to manually add tags to certain constructs in order
-    for the ASN.1 specification to be valid. Here is an example of
-    an old-style specification:</p>
-
-    <pre>
-Tags DEFINITIONS ::=
-BEGIN
-  Afters ::= CHOICE { cheese [0] IA5String,
-                      dessert [1] IA5String }
-END </pre>
-
-    <p>Without the tags (the numbers in square brackets) the ASN.1
-    compiler would refuse to compile the file.</p>
-
-    <p>In 1994 the global tagging mode AUTOMATIC TAGS was introduced.
-    By putting AUTOMATIC TAGS in the module header, the ASN.1 compiler
-    will automatically add tags when needed. Here is the same
-    specification in AUTOMATIC TAGS mode:</p>
-
-    <pre>
-Tags DEFINITIONS AUTOMATIC TAGS ::=
-BEGIN
-  Afters ::= CHOICE { cheese IA5String,
-                      dessert IA5String }
-END
-</pre>
-
-    <p>Tags will not be mentioned any more in this manual.</p>

-    <pre>

-
-    <section>
-      <marker id="BOOLEAN"></marker>
-      <title>BOOLEAN</title>
-      <p>Booleans in ASN.1  express values that can be either 
-        TRUE or FALSE.
-        The meanings assigned to TRUE or FALSE is beyond the scope 
-        of this text.          <br></br>
-
-        In ASN.1 it is possible to have:</p>
-      <pre>
-Operational ::= BOOLEAN
-      </pre>
-      <p>Assigning a value to the type Operational in Erlang is possible by 
-        using the following Erlang code:</p>
-      <code type="erl">
-Myvar1 = true,
-      </code>
-      <p>Thus, in Erlang the atoms <c>true</c> and <c>false</c> are used
-        to encode a boolean value.</p>

-
-    <section>
-      <marker id="INTEGER"></marker>
-      <title>INTEGER</title>
-      <p>ASN.1 itself specifies indefinitely large integers, and the Erlang 
-        systems with versions 4.3 and higher, support very large 
-        integers, in practice indefinitely large integers.</p>
-      <p>The concept of sub-typing can be applied to integers as well
-        as to  other ASN.1 types. The details of sub-typing are not
-        explained here, for further info see  [<cite id="X.680"></cite>]. A variety 
-        of syntaxes are allowed when defining a  type as an integer:</p>
-      <pre>
-T1 ::= INTEGER
-T2 ::= INTEGER (-2..7)
-T3 ::= INTEGER (0..MAX)
-T4 ::= INTEGER (0&lt;..MAX)
-T5 ::= INTEGER (MIN&lt;..-99)
-T6 ::= INTEGER {red(0),blue(1),white(2)}
-      </pre>
-      <p>The Erlang representation of an ASN.1 INTEGER is an integer or
-        an atom if a so called <c>Named Number List</c> (see T6 above)
-        is specified.</p>
-      <p>Below is an example of Erlang code which assigns values for the
-        above types: </p>
-      <pre>
-T1value = 0,
-T2value = 6,
-T6value1 = blue,
-T6value2 = 0,
-T6value3 = white
-      </pre>
-      <p>The Erlang variables above are now bound to valid instances of
-        ASN.1 defined types. This style of value can be passed directly 
-        to the encoder for transformation into a series of bytes.</p>
-      <p>The decoder will return an atom if the value corresponds to a

-      <pre>
-R1value1 = "2.14",
-R1value2 = {256,10,-2},
-      </pre>
-      <p>In the last line note that the tuple {256,10,-2} is the real number
-        2.56 in a special notation, which will encode faster than simply 
-        stating the number as <c>"2.56"</c>. The arity three tuple is

-      <pre>
-Notype ::= NULL
-      </pre>
-      <p>The NULL type can be assigned in Erlang:</p>
-      <pre>

-      <marker id="ENUMERATED"></marker>
-      <title>ENUMERATED</title>
-      <p>The enumerated type can be used, when the value we wish to 
-        describe, may only take one of a set of predefined values.</p>
-      <pre>
-DaysOfTheWeek ::= ENUMERATED { 
-    sunday(1),monday(2),tuesday(3),
-    wednesday(4),thursday(5),friday(6),saturday(7) }
-      </pre>
-      <p>For example to assign a weekday value in Erlang use the same atom
-        as in the <c>Enumerations</c> of the type definition:</p>
-      <pre>
-Day1 = saturday,
-      </pre>
-      <p>The enumerated type is very similar to an integer type, when
-        defined with a set of predefined values. An enumerated type
-        differs from an integer in that it may only have  specified
-        values, whereas an integer can also have any other value.</p>

-      <marker id="BIT STRING"></marker>
-      <title>BIT STRING</title>
-      <p>The BIT STRING type can be used to model information which
-        is made up of  arbitrary length series of bits. It is intended
-        to be used for a selection of flags, not for binary files.        <br></br>
-
-        In ASN.1 BIT STRING definitions may look like:
-        </p>
-      <pre>
-Bits1 ::= BIT STRING
-Bits2 ::= BIT STRING {foo(0),bar(1),gnu(2),gnome(3),punk(14)}
-      </pre>
-      <p>There are two notations available for representation of
-        BIT STRING values in Erlang and as input to the encode functions.</p>
-      <list type="ordered">
-	<item>A bitstring. By default, a BIT STRING with no
-	  symbolic names will be decoded to an Erlang bitstring.</item>
-        <item>A list of atoms corresponding to atoms in the <c>NamedBitList</c> 
-         in the BIT STRING definition. A BIT STRING with symbolic
-	 names will always be decoded to this format.</item>
-      </list>
-      <p>Example:</p>
-      <pre>
-Bits1Val1 = &lt;&lt;0:1,1:1,0:1,1:1,1:1&gt;&gt;,
-Bits2Val1 = [gnu,punk],
-Bits2Val2 = &lt;&lt;2#1110:4&gt;&gt;,
-Bits2Val3 = [bar,gnu,gnome],
-      </pre>
-      <p><c>Bits2Val2</c> and <c>Bits2Val3</c> above denote the same value.</p>
-      <p><c>Bits2Val1</c> is assigned symbolic values. The assignment means 
-        that the bits corresponding to <c>gnu</c> and <c>punk</c> i.e. bits
-        2 and 14 are set to 1 and the rest set to 0. The symbolic values
-        appear as a list of values. If a named value appears, which is not
-        specified in the type definition, a run-time error will occur.</p>
-      <p>BIT STRINGS may also be sub-typed with, for example, a SIZE
-        specification:</p>
-      <pre>
-Bits3 ::= BIT STRING (SIZE(0..31))      </pre>
-      <p>This means that no bit higher than 31 can ever be set.</p>

-      <marker id="OCTET STRING"></marker>
-      <title>OCTET STRING</title>
-      <p>The OCTET STRING is the simplest of all ASN.1 types. The
-      OCTET STRING only moves or transfers e.g. binary files or other
-      unstructured information complying to two rules.  Firstly, the
-      bytes consist of octets and secondly, encoding is not
-      required.</p>
-      <p>It is possible to have the following ASN.1 type definitions:</p>
-      <pre>
-O1 ::= OCTET STRING
-O2 ::= OCTET STRING (SIZE(28))      </pre>
-      <p>With the following example assignments in Erlang:</p>
-      <pre>
-O1Val = &lt;&lt;17,13,19,20,0,0,255,254&gt;&gt;,
-O2Val = &lt;&lt;"must be exactly 28 chars...."&gt;&gt;,</pre>
-       <p>By default, an OCTET STRING is always represented as
-       an Erlang binary. If the specification has been compiled with
-       the <c>legacy_erlang_types</c> option, the encode functions
-       will accept both lists and binaries, and the decode functions
-       will decode an OCTET STRING to a list.</p>
-    </section>

-    <section>
-      <marker id="Character Strings"></marker>
-      <title>Character Strings</title>
-      <p>ASN.1 supports a wide variety of character sets. The main difference
-        between OCTET STRINGS and the Character strings is that OCTET
-        STRINGS have no imposed semantics on the bytes delivered.</p>
-      <p>However, when using for instance the IA5String (which closely
-        resembles ASCII)  the byte 65 (in decimal
-        notation)  <em>means</em> the character 'A'.
-        </p>
-      <p>For example, if a defined type is to be a VideotexString and
-        an octet is received with the unsigned integer value X, then
-        the octet should be interpreted as specified in the standard
-        ITU-T T.100,T.101. 
-        </p>
-      <p>The  ASN.1 to Erlang compiler
-        will not determine the correct interpretation  of each BER  
-        (Basic Encoding Rules) string octet value with different
-        Character strings. Interpretation of octets is the
-        responsibility of the application. Therefore, from the BER
-        string point of view, octets appear to be very similar to
-        character strings and are compiled in the same way.
-        </p>
-      <p>It should be noted that when PER (Packed Encoding Rules) is
-        used, there is a significant difference in the encoding scheme 
-        between OCTET STRINGS and other strings. The constraints 
-        specified for a type are especially important for PER, where
-        they affect the encoding.
-        </p>
-      <p>Here are some examples:</p>
-      <pre>
-Digs ::= NumericString (SIZE(1..3))
-TextFile ::= IA5String (SIZE(0..64000))      </pre>
-      <p>with corresponding Erlang assignments:</p>
-      <pre>
-DigsVal1 = "456",
-DigsVal2 = "123",
-TextFileVal1 = "abc...xyz...",
-TextFileVal2 = [88,76,55,44,99,121 .......... a lot of characters here ....]        </pre>
-      <p>The Erlang representation for "BMPString" and
-        "UniversalString" is either a list of ASCII values or a list
-        of quadruples. The quadruple representation associates to the
-        Unicode standard representation of characters. The ASCII
-        characters are all represented by quadruples beginning with
-        three zeros like {0,0,0,65} for the 'A' character. When
-        decoding a value for these strings the result is a list of
-        quadruples, or integers when the value is an ASCII character.</p>

-      <p>The OBJECT IDENTIFIER is used whenever a unique identity is required.
-        An ASN.1 module, a transfer syntax, etc. is identified with an
-        OBJECT IDENTIFIER. Assume the example below:</p>
-      <pre>
-Oid ::= OBJECT IDENTIFIER
-      </pre>

-      <pre>
-OidVal1 = {1,2,55},
-      </pre>
-      <p>The OBJECT IDENTIFIER value is simply a tuple with the
-        consecutive values which must be integers. 
-        </p>
-      <p>The first value is limited to the values 0, 1 or 2 and the

-        is 0 or 1.
-        </p>
-      <p>The OBJECT IDENTIFIER is a very important type and it is

-      <title>SEQUENCE</title>
-      <p>The structured types of ASN.1 are constructed from other types 
-        in a manner similar to the concepts of array and struct in  C.
-                <br></br>
- A SEQUENCE in ASN.1 is
-        comparable with a struct in C and a record in Erlang. 
-        A SEQUENCE may be defined as:</p>
-      <pre>
-Pdu ::= SEQUENCE {
-   a INTEGER,
-   b REAL,
-   c OBJECT IDENTIFIER,
-   d NULL }      </pre>
-      <p>This is a 4-component structure called 'Pdu'. The major format 
-        for representation of SEQUENCE in Erlang is the record format. 
-        For each SEQUENCE and <c>SET</c> in an ASN.1 module an Erlang 
-        record declaration is generated. For <c>Pdu</c> above, a record 
-        like this is defined:</p>
-      <pre>
--record('Pdu',{a, b, c, d}).      </pre>
-      <p>The record declarations for a module <c>M</c> are placed in a 
-        separate <c>M.hrl</c> file.</p>
-      <p>Values can be assigned in Erlang as shown below:</p>
-      <pre>
-MyPdu = #'Pdu'{a=22,b=77.99,c={0,1,2,3,4},d='NULL'}.      </pre>
-      <p>The decode functions will return a record as result when decoding 
-      a <c>SEQUENCE</c> or a <c>SET</c>.</p>
-
-      <p>A <c>SEQUENCE</c> and a <c>SET</c> may contain a component
-      with a <c>DEFAULT</c> key word followed by the actual value that
-      is the default value. The <c>DEFAULT</c> keyword means that the
-      application doing the encoding can omit encoding of the value,
-      thus resulting in fewer bytes to send to the receiving
-      application.</p>
-
-      <p>An application can use the atom <c>asn1_DEFAULT</c> to indicate
-      that the encoding should be omitted for that position in
-      the SEQUENCE.</p>
-
-      <p>Depending on the encoding rules, the encoder may also compare
-      the given value to the default value and automatically omit the
-      encoding if they are equal. How much effort the encoder makes to
-      to compare the values depends on the encoding rules. The DER
-      encoding rules forbids encoding a value equal to the default value,
-      so it has a more thorough and time-consuming comparison than the
-      encoders for the other encoding rules.</p>
-
-      <p>In the following example we will use this ASN.1 specification:</p>
-      <pre>
-File DEFINITIONS AUTOMATIC TAGS ::=
-BEGIN
-Seq1 ::= SEQUENCE {
-    a INTEGER DEFAULT 1,
-    b Seq2 DEFAULT {aa TRUE, bb 15}
-}
-
-Seq2 ::= SEQUENCE {
-    aa BOOLEAN,
-    bb INTEGER
-}
-
-Seq3 ::= SEQUENCE {
-    bs BIT STRING {a(0), b(1), c(2)} DEFAULT {a, c}
-}
-END </pre>
-      <p>Here is an example where the BER encoder is able to omit encoding
-      of the default values:</p>
-      <pre>
-1> <input>asn1ct:compile('File', [ber]).</input>
-ok
-2> <input>'File':encode('Seq1', {'Seq1',asn1_DEFAULT,asn1_DEFAULT}).</input>
-{ok,&lt;&lt;48,0>>}
-3> <input>'File':encode('Seq1', {'Seq1',1,{'Seq2',true,15}}).</input>
-{ok,&lt;&lt;48,0>>}   </pre>
-
-     <p>And here is an example with a named BIT STRING where the BER
-     encoder will not omit the encoding:</p>
-     <pre>
-4> <input>'File':encode('Seq3', {'Seq3',asn1_DEFAULT).</input>
-{ok,&lt;&lt;48,0>>}
-5> <input>'File':encode('Seq3', {'Seq3',&lt;&lt;16#101:3>>).</input>
-{ok,&lt;&lt;48,4,128,2,5,160>>}     </pre>
-
-     <p>The DER encoder will omit the encoding for the same BIT STRING:</p>
-     <pre>
-6> <input>asn1ct:compile('File', [ber,der]).</input>
-ok
-7> <input>'File':encode('Seq3', {'Seq3',asn1_DEFAULT).</input>
-{ok,&lt;&lt;48,0>>}

-      <marker id="SET"></marker>
-      <title>SET</title>
-      <p>In Erlang, the SET type is used exactly as SEQUENCE. Note
-      that if the BER or DER encoding rules are used, decoding a
-      SET is slower than decoding a SEQUENCE because the components
-      must be sorted.</p>

-    <section>
-      <title>Notes about extensibility for SEQUENCE and SET</title>
-      <p>When a SEQUENCE or SET contains an extension marker and 
-        extension components like this:</p>
-      <pre>
-SExt ::= SEQUENCE {
-           a INTEGER,
-           ...,
-           b BOOLEAN }
-      </pre>
-      <p>It means that the type may get more components in newer
-        versions of the ASN.1 spec. In this case it has got a new
-        component <c>b</c>. Thus, incoming messages that will be decoded
-        may have more or fever components than this one.  
-        </p>
-      <p>The component <c>b</c> will be treated as
-        an original component when encoding a message. In this case, as
-        it is not an optional element, it must be encoded.
-        </p>
-      <p>During decoding the <c>b</c> field of the record will get the decoded 
-        value of the <c>b</c> 
-        component if present and otherwise the value <c>asn1_NOVALUE</c>.</p>

-      <title>CHOICE</title>
-      <p>The CHOICE type is a space saver and is similar to the concept of a

-      <p>Assume:</p>
-      <pre>
-SomeModuleName DEFINITIONS AUTOMATIC TAGS ::=
-BEGIN
-T ::= CHOICE {
-        x REAL,
-        y INTEGER,
-        z OBJECT IDENTIFIER }
-END </pre>
-      <p>It is then possible to assign values:</p>
-      <pre>
-TVal1 = {y,17},
-TVal2 = {z,{0,1,2}},
-      </pre>
-      <p>A CHOICE value is always represented as the tuple

-        <title>Extensible CHOICE</title>
-        <p>When a CHOICE contains an extension marker and the decoder detects
-          an unknown alternative of the CHOICE the value is represented as:</p>
-        <pre>
-{asn1_ExtAlt, BytesForOpenType}
-        </pre>
-        <p>Where <c>BytesForOpenType</c> is a list of bytes constituting the

-      <title>SET OF and SEQUENCE OF</title>
-      <p>The SET OF and SEQUENCE OF types correspond to the concept of an array
-        found in several programming languages. The Erlang syntax for
-        both of these types is straight forward. For example:</p>
-      <pre>
-Arr1 ::= SET SIZE (5) OF INTEGER (4..9) 
-Arr2 ::= SEQUENCE OF OCTET STRING      </pre>
-      <p>We may have the following in Erlang:</p>
-      <pre>
-Arr1Val = [4,5,6,7,8],
-Arr2Val = ["abc",[14,34,54],"Octets"],      </pre>
-      <p>Please note that the definition of the SET OF type implies that 
-        the order of the components is undefined, but in practice there is 
-        no difference between SET OF and SEQUENCE OF. The ASN.1 compiler 
-        for Erlang does not randomize the order of the SET OF components 
-        before encoding.</p>
-      <p>However, in case of a value of the type <c>SET OF</c>, the DER 
-        encoding format requires the elements to be sent in ascending 
-        order of their encoding, which implies an expensive sorting 
-        procedure in run-time. Therefore it is strongly recommended to 
-        use <c>SEQUENCE OF</c> instead of <c>SET OF</c> if it is possible.</p>

-      <p>The <c>EXTERNAL</c> type had a slightly different associated type
-        before 1994. [<cite id="X.691"></cite>] states that encoding shall follow
-        the older associate type. Therefore does generated encode/decode
-        functions convert values of the newer format to the older format
-        before encoding. This implies that it is allowed to use

-      <title>Embedded Named Types</title>
-      <p>The structured types previously described may very well have other named types

-        of a named ASN.1 type T in Erlang is the record syntax
-        <c>#'T'{'C'=Value}</c>. 
-        Where <c>Value</c> may be a value of yet another type T2.</p>
-      <p>For example:</p>
-      <pre>
-EmbeddedExample DEFINITIONS AUTOMATIC TAGS ::=

-    <title>Naming of Records in .hrl Files</title>
-    <p>When an ASN.1 specification is compiled all defined types of

-      as mentioned in sections above are represented as records.</p>
-    <p>Though there are some special cases of this functionality that
-      are presented below.</p>
-
-    <section>
-      <title>Embedded Structured Types</title>
-      <p>It is also possible in ASN.1 to have components that are  themselves
-        structured types.
-        For example, it is possible to have:</p>
-      <pre>
-Emb ::= SEQUENCE {
-    a SEQUENCE OF OCTET STRING,
-    b SET {
-       a INTEGER,
-       b INTEGER DEFAULT 66},
-    c CHOICE {
-       a INTEGER,
-       b FooType } }
-
-FooType ::= [3] VisibleString      </pre>
-      <p>The following records are generated because of the type <c>Emb</c>:</p>
-      <pre>
--record('Emb,{a, b, c}).
--record('Emb_b',{a, b = asn1_DEFAULT}). % the embedded SET type
-      </pre>
-      <p>Values of the <c>Emb</c> type can be assigned like this:</p>
-      <code type="none">
-V = #'Emb'{a=["qqqq",[1,2,255]], 
-           b = #'Emb_b'{a=99}, 
-           c ={b,"Can you see this"}}.
-      </code>
-      <p>For an embedded type of type SEQUENCE/SET in a SEQUENCE/SET
-        the record name is extended with an underscore and the component
-        name. If the embedded structure is deeper with SEQUENCE, SET or
-        CHOICE types in the line, each component-/alternative-name will
-        be added to the record-name.</p>
-      <p>For example:</p>
-      <pre>
-Seq ::= SEQUENCE{

-           c  INTEGER
-        }

-}      </pre>
-      <p>will result in the following record:</p>

-      <p>If the structured type has a component with an embedded
-        SEQUENCE OF/SET OF which embedded type in turn is a
-        SEQUENCE/SET it will give a record with the SEQOF/SETOF

-      <pre>
-Seq ::= SEQUENCE {
-    a SEQUENCE OF SEQUENCE {
-           b
-               }
-    c SET OF SEQUENCE {

-      <pre>
--record('Seq_a_SEQOF'{b}).
--record('Seq_c_SETOF'{d}).      </pre>
-      <p>A parameterized type should be considered as an embedded
-        type. Each time a such type is referenced an instance of it is
-        defined. Thus in the following example a record with name
-        <c>'Seq_b'</c> is generated in the .hrl file and used to hold
-        values.</p>

-      <title>Recursive Types</title>
-      <p>Types may refer to themselves. Suppose:</p>
-      <pre>
-Rec ::= CHOICE {
-     nothing NULL,
-     something SEQUENCE {
-          a INTEGER,
-          b OCTET STRING,
-          c Rec }}      </pre>
-      <p>This type is recursive; that is, it refers to itself. This is allowed 
-        in ASN.1 and the  ASN.1-to-Erlang compiler  supports this recursive
-        type. A value for this type is assigned in Erlang as shown below:</p>
-      <pre>
-V = {something,#'Rec_something'{a = 77, 
-                                b = "some octets here", 
-                                c = {nothing,'NULL'}}}.      </pre>

-    <title>ASN.1 Values</title>
-    <p>Values can be assigned to ASN.1 type within the ASN.1 code
-      itself, as opposed to the actions taken in the previous chapter where
-      a value was assigned to an ASN.1 type in Erlang. The full value
-      syntax of ASN.1 is supported and [X.680] describes in detail how
-      to assign values in ASN.1. Below is a short example:</p>
-    <pre>
-TT ::= SEQUENCE {
-   a INTEGER,
-   b SET OF OCTET STRING }
-
-tt TT ::= {a 77,b {"kalle","kula"}}    </pre>
-    <p>The value defined here could be used in several ways. 
-      Firstly, it could be used as the value in some DEFAULT component:</p>
-    <pre>
-SS ::= SET {
-    s OBJECT IDENTIFIER,
-    val TT DEFAULT tt }    </pre>
-    <p>It could also be used from inside an Erlang program. If the above ASN.1
-      code was defined in ASN.1 module <c>Values</c>, then the ASN.1 value
-      <c>tt</c> can be reached from Erlang as
-      a function call to <c>'Values':tt()</c> as in the example below.</p>
-    <pre>
-1> <input>Val = 'Values':tt().</input>
-{'TT',77,["kalle","kula"]}
-2> <input>{ok,Bytes} = 'Values':encode('TT',Val).</input>
-{ok,&lt;&lt;48,18,128,1,77,161,13,4,5,107,97,108,108,101,4,4,
-      107,117,108,97&gt;&gt;}
-4> <input>'Values':decode('TT',Bytes).</input>
-{ok,{'TT',77,["kalle","kula"]}}
-5>
-    </pre>
-    <p>The above example shows that a function is generated by the compiler 
-      that returns a valid Erlang representation of the value, even though
-      the value is of a complex type.</p>
-    <p>Furthermore, there is a macro generated for each value in the .hrl 
-      file. So, the defined value <c>tt</c> can also be extracted by 
-      <c>?tt</c> in application code.</p>
-  </section>
-
-  <section>
-    <title>Macros</title>
-    <p>MACRO is not supported as the the type is no longer part of the 
-      ASN.1 standard.</p>

-    <title>ASN.1 Information Objects (X.681)</title>
-    <p>Information Object Classes, Information Objects and Information
-      Object Sets (in the following called classes, objects and
-      object sets respectively) are defined in the standard
-      definition [<cite id="X.681"></cite>]. In the following only a brief
-      explanation is given. </p>
-    <p>These constructs makes it possible to define open types,
-      i.e. values of that type can be of any ASN.1 type. It is also
-      possible to define relationships between different types and
-      values, since classes can hold types, values, objects, object
-      sets and other classes in its fields.
-      An Information Object Class may be defined in ASN.1 as:</p>
-    <pre>
-GENERAL-PROCEDURE ::= CLASS {
-      &amp;Message,
-      &amp;Reply               OPTIONAL,
-      &amp;Error               OPTIONAL,
-      &amp;id          PrintableString UNIQUE
-}
-WITH SYNTAX {
-      NEW MESSAGE     &amp;Message
-      [REPLY           &amp;Reply]
-      [ERROR           &amp;Error]
-      ADDRESS          &amp;id
-}    </pre>
-    <p>An object is an instance of a class and an object set is a set
-      containing objects of one specified class. A definition may look like
-      below.</p>
-    <p>The object <c>object1</c> is an instance of the CLASS 
-      GENERAL-PROCEDURE and has one type field and one fixed type value 
-      field. The object <c>object2</c> also has an OPTIONAL field ERROR,
-      which is a type field.</p>
-    <pre>
-object1 GENERAL-PROCEDURE ::= {
-    NEW MESSAGE      PrintableString
-    ADDRESS          "home"
-}
-
-object2 GENERAL-PROCEDURE ::= {
-    NEW MESSAGE INTEGER
-    ERROR INTEGER
-    ADDRESS "remote"
-}    </pre>
-    <p>The field ADDRESS is a UNIQUE field. Objects in an object set must
-      have unique values in their UNIQUE field, as in GENERAL-PROCEDURES: </p>
-    <pre>
-GENERAL-PROCEDURES GENERAL-PROCEDURE ::= {
-    object1 | object2}    </pre>
-    <p>One can not encode a class, object or object set, only referring to
-      it when defining other ASN.1 entities. Typically one refers to a
-      class and to object sets by table constraints and component
-      relation constraints [<cite id="X.682"></cite>] in ASN.1 types, as in: </p>
-    <pre>
-StartMessage  ::= SEQUENCE {
-    msgId  GENERAL-PROCEDURE.&amp;id  ({GENERAL-PROCEDURES}),
-    content GENERAL-PROCEDURE.&amp;Message ({GENERAL-PROCEDURES}{@msgId}),
-    }    </pre>
-    <p>In the type <c>StartMessage</c> the constraint following the
-      <c>content</c> field tells that in a value of type
-      <c>StartMessage</c> the value in the <c>content</c> field must
-      come from the same object that is chosen by the <c>msgId</c>
-      field.</p>
-    <p>So, the value <c>#'StartMessage'{msgId="home",content="Any Printable String"}</c> is legal to encode as a StartMessage
-      value, while the value <c>#'StartMessage'{msgId="remote", content="Some String"}</c> is illegal since the constraint
-      in StartMessage tells that when you have chosen a value from a 
-      specific object in the object set GENERAL-PROCEDURES in the 
-      msgId field you have to choose a value from that same object in
-      the content field too. In this second case it should have been 
-      any INTEGER value.</p>
-    <p><c>StartMessage</c> can in the <c>content</c> field be
-      encoded with a value of any type that an object in the
-      <c>GENERAL-PROCEDURES</c> object set has in its <c>NEW MESSAGE</c> field. This field refers to a type field
-      <c>&amp;Message</c> in the class. The <c>msgId</c> field is always
-      encoded as a PrintableString, since the field refers to a fixed type
-      in the class.</p>
-    <p>In practice, object sets are usually declared to be extensible so
-    so that more objects can be added to the set later. Extensibility is
-    indicated like this:</p>
-    <pre>
-GENERAL-PROCEDURES GENERAL-PROCEDURE ::= {
-    object1 | object2, ...}    </pre>
-     <p>When decoding a type that uses an extensible set constraint,
-     there is always the possibility that the value in the UNIQUE
-     field is unknown (i.e. the type has been encoded with a later
-     version of the ASN.1 specification). When that happens, the
-     unencoded data will be returned wrapped in a tuple like this:</p>
-
-     <pre>
-{asn1_OPENTYPE,Binary}</pre>
-     <p>where <c>Binary</c> is an Erlang binary that contains the encoded
-     data. (If the option <c>legacy_erlang_types</c> has been given,
-     just the binary will be returned.)</p>
-  </section>

-  <section>
-    <title>Parameterization (X.683)</title>
-    <p>Parameterization, which is defined in the standard [<cite id="X.683"></cite>], can be used when defining types, values, value
-      sets, information object classes, information objects or
-      information object sets. 
-      A part of a definition can be supplied as a parameter. For
-      instance, if a Type is used in a definition with certain
-      purpose, one want the type-name to express the intention. This
-      can be done with parameterization.</p>
-    <p>When many types (or another ASN.1 entity) only differs in some
-      minor cases, but the structure of the types are similar, only
-      one general type can be defined and the differences may be supplied
-      through parameters. </p>
-    <p>One example of use of parameterization is:</p>
-    <pre>
-General{Type} ::= SEQUENCE
-{
-     number     INTEGER,
-     string     Type
-}
-      
-T1 ::= General{PrintableString}
-
-T2 ::= General{BIT STRING}
-    </pre>
-    <p>An example of a value that can be encoded as type T1 is {12,"hello"}.</p>
-    <p>Note that the compiler does not generate encode/decode functions for
-      parameterized types, but only for the instances of the parameterized
-      types. Therefore, if a file contains the types General{}, T1 and T2 above,
-      encode/decode functions will only be generated for T1 and T2.
-      </p>

-          <c>SetOfFiles.hrl, SetOfFiles.erl and SetOfFiles.asn1db</c>.</p>
-        <p>Sometimes in a system of ASN.1 modules there are different

-        <p>Another unwanted effect that may occur in multi file compilation

-          name and the original module name concatenated.</p>

+%%% We represent sets as a union of strictly disjoint ranges:
+%%%
+%%%   {set,[Range]}
+%%%
+%%% A range is represented as:
+%%%
+%%%   Range = {a_range,UpperBound} | {range,LowerBound,UpperBound}
+%%%
+%%% We don't use the atom 'MIN' to represent MIN, because atoms
+%%% compare higher than integer. Instead we use {a_range,UpperBound}
+%%% to represent MIN..UpperBound. We represent MAX as 'MAX' because
+%%% 'MAX' compares higher than any integer.
+%%%
+%%% The ranges are sorted in term order. The ranges must not overlap
+%%% or be adjacent to each other. This invariant is established when
+%%% creating sets, and maintained by the intersection and union
+%%% operators.
+%%%
+%%% Example of invalid set representaions:
+%%%
+%%%   [{range,0,10},{range,5,10}]    %Overlapping ranges
+%%%   [{range,0,5},{range,6,10}]     %Adjancent ranges
+%%%   [{range,10,20},{a_range,100}]  %Not sorted

+-- AlgorithmIdentifier

+--
+-- The first parameter represents the type of the algorithm being
+--    used.
+-- The second parameter represents an object set containing the
+--    algorithms that may occur in this situation.
+--    The initial list of required algorithms should occur to the
+--      left of an extension marker; all other algorithms should
+--      occur to the right of an extension marker.
+--
+-- The object class ALGORITHM can be used for generic unspecified
+--     items.
+-- If new ALGORITHM classes are defined, the fields &id and &Params
+--     need to be present as fields in the object in order to use
+--     this parameterized type.

+
+AlgorithmIdentifier{ALGORITHM-TYPE, ALGORITHM-TYPE:AlgorithmSet} ::=

+
+--  S/MIME Capabilities
+--
+--  We have moved the SMIME-CAPS from the module for RFC 3851 to here
+--  because it is used in RFC 4262 (X.509 Certificate Extension for
+--  S/MIME Capabilities)
+--
+--
+--  This class is used to represent an S/MIME capability.  S/MIME
+--  capabilities are used to represent what algorithm capabilities
+--  an individual has.  The classic example was the content encryption
+--  algorithm RC2 where the algorithm id and the RC2 key lengths
+--  supported needed to be advertised, but the IV used is not fixed.
+--  Thus, for RC2 we used
+--
+--  cap-RC2CBC SMIME-CAPS ::= {
+--      TYPE INTEGER ( 40 | 128 ) IDENTIFIED BY rc2-cbc }
+--
+--  where 40 and 128 represent the RC2 key length in number of bits.
+--
+--  Another example where information needs to be shown is for
+--  RSA-OAEP where only specific hash functions or mask generation
+--  functions are supported, but the saltLength is specified by the
+--  sender and not the recipient.  In this case, one can either
+--  generate a number of capability items,
+--  or a new S/MIME capability type could be generated where
+--  multiple hash functions could be specified.
+--
+--
+--  SMIME-CAP
+--
+--  This class is used to associate the type that describes the
+--  capabilities with the object identifier.
+--
+
+SMIME-CAPS ::= CLASS {
+    &id         OBJECT IDENTIFIER UNIQUE,

       The <c>ct</c> interface functions can be called from the Erlang shell,
       or from any Erlang function, on any supported platform.</p>
 
-    <p>A legacy Bourne shell script - named run_test - exists,
-      which may be manually generated and installed. This script may be used
-      instead of the ct_run program mentioned above, e.g. if the user
-      wishes to modify or customize the Common Test start flags in a simpler
-      way than making changes to the ct_run C program.</p>
-
     <p>The Common Test application is installed with the Erlang/OTP
       system and no additional installation step is required to start using
-      Common Test by means of the ct_run executable program, and/or the interface
-      functions in the <c>ct</c> module. If you wish to use the legacy Bourne
-      shell script version run_test, however, this script needs to be
-      generated first, according to the instructions below.</p>
-
-    <note><p>Before reading on, please note that since Common Test version
-	1.5, the run_test shell script is no longer required for starting
-	tests with Common Test from the OS command line. The ct_run
-	program (descibed above) is the new recommended command line interface
-	for Common Test. The shell script exists mainly for legacy reasons and
-	may not be updated in future releases of Common Test. It may even be removed.
-    </p></note>
-
-    <p>Optional step to generate a shell script for starting Common Test:</p>
-    <p>To generate the run_test shell script, navigate to the
-      <c><![CDATA[common_test-<vsn>]]></c> directory, located among the other
-      OTP applications (under the OTP lib directory). Here execute the
-      <c>install.sh</c> script with argument <c>local</c>:</p>
-
-    <p><c>
-	$ ./install.sh local
-    </c></p>
-    
-    <p>This generates the executable run_test script in the
-      <c><![CDATA[common_test-<vsn>/priv/bin]]></c> directory. The script
-      will include absolute paths to the Common Test and Test Server
-      application directories, so it's possible to copy or move the script to
-      a different location on the file system, if desired, without having to
-      update it. It's of course possible to leave the script under the
-      <c>priv/bin</c> directory and update the PATH variable accordingly (or
-      create a link or alias to it).</p>
-
-    <p>If you, for any reason, have copied Common Test and Test Server
-      to a different location than the default OTP lib directory, you can
-      generate a run_test script with a different top level directory,
-      simply by specifying the directory, instead of <c>local</c>, when running
-      <c>install.sh</c>. Example:</p>
-
-    <p><c>
-	$ install.sh /usr/local/test_tools
-    </c></p>
-
-    <p>Note that the <c><![CDATA[common_test-<vsn>]]></c> and
-      <c><![CDATA[test_server-<vsn>]]></c> directories must be located under the
-      same top directory. Note also that the install script does not copy files
-      or update environment variables. It only generates the run_test
-      script.</p>
-    
-    <p>Whenever you install a new version of Erlang/OTP, the run_test
-      script needs to be regenerated, or updated manually with new directory names
-      (new version numbers), for it to "see" the latest Common Test and Test Server
-      versions.</p>

+	    "skipped" to CT Hook functions, but "successful" to event

+	    that now the tuple {'EXIT',ReasonForProcessTermination}
+	    is passed instead. This makes it much easier in the CT
+	    post hook functions to distinguish a failure of this sort
+	    from other types of errors and from the return value of a

+	    buffer. The polling is controlled by two new telnet
+	    config values, which are documented in the ct_telnet
+	    reference manual. The polling mechanism is disabled by
+	    default (making the get_data/1 function backwards

+    <p>
+      The <c>-dialyzer()</c> attribute can be used for turning off
+      warnings in a module by specifying functions or warning options.
+      For example, to turn off all warnings for the function
+      <c>f/0</c>, include the following line:
+    </p>
+<code type="none">
+-dialyzer({nowarn_function, f/0}).
+</code>
+    <p>To turn off warnings for improper lists, add the following line
+      to the source file:
+    </p>
+<code type="none">
+-dialyzer(no_improper_lists).
+</code>
+    <p>The <c>-dialyzer()</c> attribute is allowed after function
+    declarations. Lists of warning options or functions are allowed:
+    </p>
+<code type="none">
+-dialyzer([{nowarn_function, [f/0]}, no_improper_lists]).
+</code>
+    <p>
+      Warning options can be restricted to functions:
+    </p>
+<code type="none">
+-dialyzer({no_improper_lists, g/0}).
+</code>
+<code type="none">
+-dialyzer({[no_return, no_match], [g/0, h/0]}).
+</code>
+    <p>
+      For help on the warning options use <c>dialyzer -Whelp</c>. The
+      options are also enumerated <seealso
+      marker="#gui/1">below</seealso> (<c>WarnOpts</c>).
+    </p>
+    <note>
+      <p>
+        The <c>-dialyzer()</c> attribute is not checked by the Erlang
+              Compiler, but by the Dialyzer itself.
+      </p>
+    </note>
+    <note>
+      <p>
+        The warning option <c>-Wrace_conditions</c> has no effect when
+        set in source files.
+      </p>
+    </note>
+    <p>
+      The <c>-dialyzer()</c> attribute can also be used for turning on
+      warnings. For instance, if a module has been fixed regarding
+      unmatched returns, adding the line
+    </p>
+<code type="none">
+-dialyzer(unmatched_returns).
+</code>
+    <p>
+      can help in assuring that no new unmatched return warnings are
+      introduced.

+	    RFC 6773 changed the default port and transport, but the
+	    RFC 3588 defaults were used even if the RFC 6733 common
+	    dictionary was in use. The RFC 3588 defaults are now only
+	    used when the common dictionary is
+	    diameter_gen_base_rfc3588.</p>
+          <p>
+	    Both RFC 3588 and 6733 disallow
+	    transport=udp;protocol=diameter. Encode of the
+	    combination now fails.</p>
+          <p>
+	    Decode of ports numbers outside the range 0-65535 and
+	    fully qualified domain names longer than 255 octets now
+	    fails.</p>
+          <p>
+	    Note that RFC 3588 is obsolete, and that there is a
+	    diameter_gen_base_rfc6733. The change in defaults is a
+	    potential interoperability problem when moving to RFC
+	    6733 with peers that do not send all URI components. The
+	    fact that 6733 allows 5xxx result codes in answer
+	    messages setting the E-bit, which RFC 3588 doesn't, is
+	    another.</p>

+	    Add service_opt() string_decode.</p>
+          <p>
+	    To disable the decode of potentially large binaries to

+	    exhausted given sufficiently malicious peers.</p>
+          <p>
+	    The value is a boolean(), true being the default for
+	    backwards compatibility. Setting false causes both
+	    diameter_caps records and decoded messages to contain
+	    binary() in relevant places that previously had string():
+	    diameter_app(3) callbacks need to be prepared for the
+	    change.</p>

+          <p>
+	    RFC 6733 is imprecise, but the tone is that messages
+	    received after DPR are an exception to be dealt with only
+	    because of the possibility of unordered delivery over
+	    SCTP. As a consequence, and because a request following
+	    DPR is unlikely to be answered due to the impending loss
+	    of the peer connection, discard outgoing requests
+	    following an outgoing or incoming DPR. Incoming requests
+	    are also discarded, with the exception of DPR itself.
+	    Answers are sent and received as usual.</p>

+	    Fix two bugs in HiPE compiler regarding floating-points,
+	    both leading to crash during compilation. The
+	    target-specific code generators failed to handle integer
+	    to floating-point conversion instructions with constant
+	    operands. The middle-end could use an incorrect
+	    representation for copies between floating-point
+	    registers.</p>

-      <note>
-        <p>Having the server parse HTML pages is a double edged sword!
-          It can be costly for a heavily loaded server to perform
-          parsing of HTML pages while sending them. Furthermore, it can
-          be considered a security risk to have average users executing 
-          commands in the name of the  Erlang node user. Carefully
-          consider these items before activating server-side includes.</p>

-        <title>SERVER-SIDE INCLUDES (SSI) SETUP</title>
-        <p>The server must be told which filename extensions to be used
-          for the parsed files. These files, while very similar to HTML,
-          are not HTML and are thus not treated the same. Internally, the
-          server uses the magic MIME type <c>text/x-server-parsed-html</c>
-          to identify parsed documents. It will then perform a format
-          conversion to change these files into HTML for the
-          client. Update the <c>mime.types</c> file, as described in the
-          Mime Type Settings, to tell the server which extension to use
-          for parsed files, for example:
-          </p>
-        <pre>
-	text/x-server-parsed-html shtml shtm
-        </pre>
-        <p>This makes files ending with <c>.shtml</c> and <c>.shtm</c>
-          into parsed files. Alternatively, if the performance hit is not a
-          problem, <em>all</em> HTML pages can be marked as parsed:
-          </p>
-        <pre>
-	text/x-server-parsed-html html htm

-        <title>Server-Side Includes (SSI) Format</title>
-        <p>All server-side include directives to the server are formatted
-          as SGML comments within the HTML page. This is in case the
-          document should ever  find itself in the client's hands
-          unparsed. Each directive has the following format:
-          </p>
-        <pre>
-	&lt;!--#command tag1="value1" tag2="value2" --&gt;
-        </pre>
-        <p>Each command takes different arguments, most only accept one
-          tag at a time. Here is a breakdown of the commands and their
-          associated tags:
-          </p>
-        <p>The config directive controls various aspects of the
-          file parsing. There are two valid tags:
-          </p>
-        <taglist>
-          <tag><c>errmsg</c></tag>
-          <item>
-            <p>controls the message sent back to the client if an
-              error occurred while parsing the document. All errors are
-              logged in the server's error log.</p>
-          </item>
-          <tag><c>sizefmt</c></tag>
-          <item>
-            <p>determines the format used to  display the size of
-              a file. Valid choices are <c>bytes</c> or
-              <c>abbrev</c>. <c>bytes</c> for a formatted byte count
-              or <c>abbrev</c> for an abbreviated version displaying
-              the number of kilobytes.</p>
-          </item>
-        </taglist>
-        <p>The include directory 
-          will insert the text of a document into the parsed
-          document. This command accepts two tags:</p>
-        <taglist>
-          <tag><c>virtual</c></tag>
-          <item>
-            <p>gives a virtual path to a document on the
-              server. Only normal files and other parsed documents can
-              be accessed in this way.</p>
-          </item>
-          <tag><c>file</c></tag>
-          <item>
-            <p>gives a pathname relative to the current
-              directory. <c>../</c> cannot be used in this pathname, nor
-              can absolute paths. As above, you can send other parsed
-              documents, but you cannot send CGI scripts.</p>
-          </item>
-        </taglist>
-        <p>The echo directive prints the value of one of the include
-          variables (defined below). The only valid tag to this
-          command is <c>var</c>, whose value is the name of the
-          variable you wish to echo.</p>
-        <p>The fsize directive prints the size of the specified
-          file. Valid tags are the same as with the <c>include</c>
-          command. The resulting format of this command is subject
-          to the <c>sizefmt</c> parameter to the <c>config</c>
-          command.</p>
-        <p>The lastmod directive prints the last modification date of
-          the specified file. Valid tags are the same as with the
-          <c>include</c> command.</p>
-        <p>The exec directive executes a given shell command or CGI
-          script. Valid tags are:</p>
-        <taglist>
-          <tag><c>cmd</c></tag>

-            <p>executes the given string using <c>/bin/sh</c>. All

-  <p>This chapter briefly describes erlang records derived from ASN1
-  specifications used to handle <c> X509 certificates</c> and <c>CertificationRequest</c>.
- The intent is to describe the data types
-and not to specify the semantics of each component. For information on the
-semantics, please see <url
-  href="http://www.ietf.org/rfc/rfc5280.txt">RFC 5280</url> and
-  <url href="http://www.ietf.org/rfc/rfc5967.txt">PKCS-10</url>.

-
-  <p>Use the following include directive to get access to the
-    records and constant macros (OIDs) described in the following sections.</p>
-  
-  <code> -include_lib("public_key/include/public_key.hrl"). </code>
-
-  <p>The used ASN1 specifications are available <c>asn1</c> subdirectory

+
+<section>
+    <title>SSH Protocol Overview</title>
+
+    <p>Conceptually, the SSH protocol can be partitioned into four
+    layers:</p>
+
+    <image file="SSH_protocols.png">
+      <icaption>SSH Protocol Architecture</icaption>
+    </image>
+
+    <section>
+      <title>Transport Protocol</title>
+
+      <p>The SSH Transport Protocol is a secure, low-level transport.
+      It provides strong encryption, cryptographic host
+      authentication, and integrity protection. A minimum of
+      Message Authentication Code (MAC) and encryption
+      algorithms are supported. For details, see the
+      <seealso marker="ssh">ssh(3)</seealso> manual page in <c>ssh</c>.</p>
+    </section>
+
+    <section>
+      <title>Authentication Protocol</title>
+
+      <p>The SSH Authentication Protocol is a general-purpose user
+      authentication protocol run over the SSH Transport Layer
+      Protocol. The <c>ssh</c> application supports user authentication as follows:
+      </p>
+      <list type="bulleted">
+	<item>
+	  Using public key technology. RSA and DSA, X509-certificates
+	  are not supported.
+	</item>
+	<item>
+	  Using keyboard-interactive authentication.
+	  This is suitable for interactive authentication methods
+	  that do not need any special software support on the client side.
+	  Instead, all authentication data is entered from the keyboard.
+	</item>
+	<item>
+	  Using a pure password-based authentication scheme.
+	  Here, the plain text password is encrypted before sent
+	  over the network.
+	</item>
+      </list>
+      <p>Several configuration options for
+      authentication handling are available in
+      <seealso marker="ssh#connect-3">ssh:connect/[3,4]</seealso>
+      and <seealso marker="ssh#daemon-2">ssh:daemon/[2,3]</seealso>.</p>
+      <p>
+      The public key handling can be customized by implementing
+      the following behaviours from <c>ssh</c>:</p>
+      <list type="bulleted">
+	<item>Module
+      <seealso marker="ssh_client_key_api">ssh_client_key_api</seealso>.

+	</item>
+      </list>
+    </section>
+
+    <section>
+      <title>Connection Protocol</title>
+
+      <p>The SSH Connection Protocol provides application-support
+      services over the transport pipe, for example, channel multiplexing,
+      flow control, remote program execution, signal propagation, and
+      connection forwarding. Functions for handling the SSH
+      Connection Protocol can be found in the module <seealso
+      marker="ssh_connection">ssh_connection</seealso> in <c>ssh</c>.
+      </p>
+    </section>
+
+    <section>
+      <title>Channels</title>
+
+      <p>All terminal sessions, forwarded connections, and so on, are
+      channels. Multiple channels are multiplexed into a single
+      connection. All channels are flow-controlled. This means that no
+      data is sent to a channel peer until a message is received to
+      indicate that window space is available.
+      The <em>initial window size</em> specifies how many bytes of channel
+      data that can be sent to the channel peer without adjusting the
+      window. Typically, an SSH client opens a channel, sends data (commands),
+      receives data (control information), and then closes the channel.
+      The <seealso marker="ssh_channel">ssh_channel</seealso> behaviour
+      handles generic parts of SSH channel management. This makes it easy
+      to write your own SSH client/server processes that use flow-control
+      and thus opens for more focus on the application logic.
+      </p>
+
+      <p>Channels come in the following three flavors:</p>
+
+      <list type="bulleted">
+	<item><em>Subsystem</em> - Named services that can be run as
+	part of an SSH server, such as SFTP <seealso
+	marker="ssh_sftpd">(ssh_sftpd)</seealso>, that is built into the
+	SSH daemon (server) by default, but it can be disabled. The Erlang <c>ssh</c>
+	daemon can be configured to run any Erlang-
+	implemented SSH subsystem.
+	</item>
+	<item><em>Shell</em> - Interactive shell. By default the
+	Erlang daemon runs the Erlang shell. The shell can be customized by
+	providing your own read-eval-print loop. You can also provide your
+	own Command-Line Interface (CLI) implementation,
+	but that is much more work.
+	</item>
+	<item><em>Exec</em> - One-time remote execution of commands. See function
+	<seealso marker="ssh_connection#exec-4">ssh_connection:exec/4</seealso>
+	for more information.</item>
+      </list>
+    </section>

+	    The PEM cache is now validated by a background process,
+	    instead of always keeping it if it is small enough and
+	    clearing it otherwise. That strategy required that small
+	    caches where cleared by API function if a file changes on
+	    disk.</p>
+          <p>

+	    Add padding check for TLS-1.0 to remove Poodle
+	    vulnerability from TLS 1.0, also add the option
+	    padding_check. This option only affects TLS-1.0
+	    connections and if set to false it disables the block

+  <description>
+    <p>
+      When SSL/TLS performs certificate path validation according to
+      <url href="http://www.ietf.org/rfc/rfc5280.txt">RFC 5280 </url>
+      it should also perform CRL validation checks. To enable the CRL
+      checks the application needs access to CRLs. A database of CRLs
+      can be set up in many different ways. This module provides the
+      behavior of the API needed to integrate an arbitrary CRL cache
+      with the erlang ssl application. It is also used by the
+      application itself to provide a simple default implementation of
+      a CRL cache.

-      and STDLIB applications. Such a script is located in the
-      Erlang distributions bin directory. The source for the script
-      can be found under the Erlang installation top directory under
-      <c><![CDATA[releases/<OTP version>/start_clean.rel]]></c>. Copy that

-      and add the applications crypto, public_key and SSL with their current version numbers
-      after the STDLIB application.</p>

+    <title>Purpose</title>
+    <p>Transport Layer Security (TLS) and its predecessor, the Secure
+    Sockets Layer (SSL), are cryptographic protocols designed to
+    provide communications security over a computer network. The protocols use
+    use X.509 certificates and hence public key (asymmetric) cryptography to
+    authenticate the counterpart with whom they communicate,
+    and to exchange a symmetric key for payload encryption. The protocol provides
+    data/message confidentiality (encryption), integrity (through message authentication code checks)
+    and host verification (through certificate path validation).</p>

+    Abstract Datatype for the Annotations of the Erlang Compiler
+  </modulesummary>
+
+  <description>
+    <p>This module implements an abstract type that is used by the
+      Erlang Compiler and its helper modules for holding data such as
+      column, line number, and text. The data type is a collection of
+      <marker id="annotations"><em>annotations</em></marker> as
+      described in the following.</p>
+    <p>The Erlang Token Scanner returns tokens with a subset of
+      the following annotations, depending on the options:</p>
+    <taglist>
+      <tag><c>column</c></tag>
+      <item><p>The column where the token begins.</p></item>
+      <tag><c>location</c></tag>
+      <item><p>The line and column where the token begins, or
+        just the line if the column unknown.</p>
+      </item>
+      <tag><c>text</c></tag>
+      <item><p>The token's text.</p></item>
+    </taglist>
+    <p>From the above the following annotation is derived:</p>
+    <taglist>
+      <tag><c>line</c></tag>
+      <item><p>The line where the token begins.</p></item>
+    </taglist>
+    <p>Furthermore, the following annotations are supported by
+      this module, and used by various modules:</p>
+    <taglist>
+      <tag><c>file</c></tag>
+      <item><p>A filename.</p></item>
+      <tag><c>generated</c></tag>
+      <item><p>A Boolean indicating if the abstract code is
+        compiler generated. The Erlang Compiler does not emit warnings
+        for such code.</p>
+      </item>
+      <tag><c>record</c></tag>
+      <item><p>A Boolean indicating if the origin of the abstract
+        code is a record. Used by Dialyzer to assign types to tuple
+        elements.</p>
+      </item>
+    </taglist>
+    <p>The functions
+      <seealso marker="erl_scan#column/1">column()</seealso>,
+      <seealso marker="erl_scan#end_location/1">end_location()</seealso>,
+      <seealso marker="erl_scan#line/1">line()</seealso>,
+      <seealso marker="erl_scan#location/1">location()</seealso>, and
+      <seealso marker="erl_scan#text/1">text()</seealso>
+      in the <c>erl_scan</c> module can be used for inspecting
+      annotations in tokens.</p>
+    <p>The functions
+      <seealso marker="erl_parse#map_anno/2">map_anno()</seealso>,
+      <seealso marker="erl_parse#fold_anno/3">fold_anno()</seealso>,
+      <seealso marker="erl_parse#mapfold_anno/3">mapfold_anno()</seealso>,
+      <seealso marker="erl_parse#new_anno/1">new_anno()</seealso>,
+      <seealso marker="erl_parse#anno_from_term/1">
+      anno_from_term()</seealso>, and
+      <seealso marker="erl_parse#anno_to_term/1">
+      anno_to_term()</seealso> in the <c>erl_parse</c> module can be
+      used for manipulating annotations in abstract code.

+  <description>
+    <p>Random number generator.</p>
+
+    <p>The module contains several different algorithms and can be
+    extended with more in the future.  The current uniform
+    distribution algorithms uses the
+    <url href="http://xorshift.di.unimi.it">
+    scrambled Xorshift algorithms by Sebastiano Vigna</url> and the
+    normal distribution algorithm uses the
+    <url href="http://www.jstatsoft.org/v05/i08">
+      Ziggurat Method by Marsaglia and Tsang</url>.
+    </p>
+
+    <p>The implemented algorithms are:</p>
+    <taglist>
+      <tag><c>exsplus</c></tag> <item>Xorshift116+, 58 bits precision and period of 2^116-1.</item>
+      <tag><c>exs64</c></tag> <item>Xorshift64*, 64 bits precision and a period of 2^64-1.</item>
+      <tag><c>exs1024</c></tag> <item>Xorshift1024*, 64 bits precision and a period of 2^1024-1.</item>
+    </taglist>
+
+    <p>The current default algorithm is <c>exsplus</c>. The default
+    may change in future. If a specific algorithm is required make
+    sure to always use <seealso marker="#seed-1">seed/1</seealso>
+    to initialize the state.
+    </p>
+
+    <p>Every time a random number is requested, a state is used to
+    calculate it and a new state produced. The state can either be
+    implicit or it can be an explicit argument and return value.
+    </p>
+
+    <p>The functions with implicit state use the process dictionary
+    variable <c>rand_seed</c> to remember the current state.</p>
+
+    <p>If a process calls <seealso marker="#uniform-0">uniform/0</seealso> or
+    <seealso marker="#uniform-1">uniform/1</seealso> without
+    setting a seed first, <seealso marker="#seed-1">seed/1</seealso>
+    is called automatically with the default algorithm and creates a
+    non-constant seed.</p>
+
+    <p>The functions with explicit state never use the process
+    dictionary.</p>
+
+    <p>Examples:</p>
+    <pre>
+      %% Simple usage. Creates and seeds the default algorithm
+      %% with a non-constant seed if not already done.
+      R0 = rand:uniform(),
+      R1 = rand:uniform(),
+
+      %% Use a given algorithm.
+      _ = rand:seed(exs1024),
+      R2 = rand:uniform(),
+
+      %% Use a given algorithm with a constant seed.
+      _ = rand:seed(exs1024, {123, 123534, 345345}),
+      R3 = rand:uniform(),
+
+      %% Use the functional api with non-constant seed.
+      S0 = rand:seed_s(exsplus),
+      {R4, S1} = rand:uniform_s(S0),
+
+      %% Create a standard normal deviate.
+      {SND0, S2} = rand:normal_s(S1),
+    </pre>
+
+    <note><p>This random number generator is not cryptographically
+    strong. If a strong cryptographic random number generator is
+    needed, use one of functions in the
+    <seealso marker="crypto:crypto">crypto</seealso>
+    module, for example <c>crypto:rand_bytes/1</c>.</p></note>

-      {@link erl_syntax:class_qualifier/2. class-qualifier patterns}.</li>

-<p>News in 1.1:
-<ul>
-  <li>Module {@link erl_tidy}: check or tidy either a single module, or a
-    whole directory tree recursively. Rewrites and reformats the code
-    without losing comments or expanding macros. Safe mode allows
-    generating reports without modifying files.</li>
-  <li>Module {@link erl_syntax_lib}: contains support functions for easier
-    analysis of the source code structure.</li>
-  <li>Module {@link epp_dodger}: Bypasses the Erlang preprocessor - avoids
-    macro expansion, file inclusion, conditional compilation, etc.
-    Allows you to find/modify particular definitions/applications of
-    macros, and other things previously not possible.</li>

+```erl_tidy:dir("any-erlang-source-dir", [test, old_guard_tests]).'''

+%%
+%% @doc Metaprogramming in Erlang.
+%% Merl is a more user friendly interface to the `erl_syntax' module, making
+%% it easy both to build new ASTs from scratch and to
+%% match and decompose existing ASTs. For details that are outside the scope
+%% of Merl itself, please see the documentation of {@link erl_syntax}.
+%%
+%% == Quick start ==
+%%
+%% To enable the full power of Merl, your module needs to include the Merl
+%% header file:
+%% ```-include_lib("syntax_tools/include/merl.hrl").'''
+%%
+%% Then, you can use the `?Q(Text)' macros in your code to create ASTs or match
+%% on existing ASTs. For example:
+%% ```Tuple = ?Q("{foo, 42}"),
+%%    ?Q("{foo, _@Number}") = Tuple,
+%%    Call = ?Q("foo:bar(_@Number)")'''
+%%
+%% Calling `merl:print(Call)' will then print the following code:
+%% ```foo:bar(42)'''
+%%
+%% The `?Q' macros turn the quoted code fragments into ASTs, and lifts
+%% metavariables such as `_@Tuple' and `_@Number' to the level of your Erlang
+%% code, so you can use the corresponding Erlang variables `Tuple' and `Number'
+%% directly. This is the most straightforward way to use Merl, and in many
+%% cases it's all you need.
+%%
+%% You can even write case switches using `?Q' macros as patterns. For example:
+%% ```case AST of
+%%        ?Q("{foo, _@Foo}") -> handle(Foo);
+%%        ?Q("{bar, _@Bar}") when erl_syntax:is_integer(Bar) -> handle(Bar);
+%%        _ -> handle_default()
+%%    end'''
+%%
+%% These case switches only allow `?Q(...)' or `_' as clause patterns, and the
+%% guards may contain any expressions, not just Erlang guard expressions.
+%%
+%% If the macro `MERL_NO_TRANSFORM' is defined before the `merl.hrl' header
+%% file is included, the parse transform used by Merl will be disabled, and in
+%% that case, the match expressions `?Q(...) = ...', case switches using
+%% `?Q(...)' patterns, and automatic metavariables like `_@Tuple' cannot be
+%% used in your code, but the Merl macros and functions still work. To do
+%% metavariable substitution, you need to use the `?Q(Text, Map)' macro, e.g.:
+%% ```Tuple = ?Q("{foo, _@bar, _@baz}", [{bar, Bar}, {baz,Baz}])'''
+%%
+%% The text given to a `?Q(Text)' macro can be either a single string, or a
+%% list of strings. The latter is useful when you need to split a long
+%% expression over multiple lines, e.g.:
+%% ```?Q(["case _@Expr of",
+%%        "  {foo, X} -> f(X);",
+%%        "  {bar, X} -> g(X)",
+%%        "  _ -> h(X)"
+%%        "end"])'''
+%% If there is a syntax error somewhere in the text (like the missing semicolon
+%% in the second clause above) this allows Merl to generate an error message
+%% pointing to the exact line in your source code. (Just remember to
+%% comma-separate the strings in the list, otherwise Erlang will concatenate
+%% the string fragments as if they were a single string.)
+%%
+%% == Metavariable syntax ==
+%%
+%% There are several ways to write a metavariable in your quoted code:
+%% <ul>
+%%   <li>Atoms starting with `@', for example `` '@foo' '' or `` '@Foo' ''</li>
+%%   <li>Variables starting with `_@', for example `_@bar' or `_@Bar'</li>
+%%   <li>Strings starting with ``"'@'', for example ``"'@File"''</li>
+%%   <li>Integers starting with 909, for example `9091' or `909123'</li>
+%% </ul>
+%% Following the prefix, one or more `_' or `0' characters may be used to
+%% indicate "lifting" of the variable one or more levels, and after that, a `@'
+%% or `9' character indicates a glob metavariable (matching zero or more
+%% elements in a sequence) rather than a normal metavariable. For example:
+%% <ul>
+%%   <li>`` '@_foo' '' is lifted one level, and `_@__foo' is lifted two
+%%       levels</li>
+%%   <li>`_@@@@bar' is a glob variable, and `_@_@bar' is a lifted glob
+%%       variable</li>
+%%   <li>`90901' is a lifted variable,`90991' is a glob variable, and `9090091'
+%%       is a glob variable lifted two levels</li>
+%% </ul>
+%% (Note that the last character in the name is never considered to be a lift
+%% or glob marker, hence, `_@__' and `90900' are only lifted one level, not
+%% two. Also note that globs only matter for matching; when doing
+%% substitutions, a non-glob variable can be used to inject a sequence of
+%% elements, and vice versa.)
+%%
+%% If the name after the prefix and any lift and glob markers is `_' or `0',
+%% the variable is treated as an anonymous catch-all pattern in matches. For
+%% example, `_@_', `_@@@@_', `_@__', or even `_@__@_'.
+%%
+%% Finally, if the name without any prefixes or lift/glob markers begins with
+%% an uppercase character, as in `_@Foo' or `_@_@Foo', it will become a
+%% variable on the Erlang level, and can be used to easily deconstruct and
+%% construct syntax trees:
+%% ```case Input of
+%%        ?Q("{foo, _@Number}") -> ?Q("foo:bar(_@Number)");
+%%        ...'''
+%% We refer to these as "automatic metavariables". If in addition the name ends
+%% with `@', as in `_@Foo@', the value of the variable as an Erlang term will
+%% be automatically converted to the corresponding abstract syntax tree when
+%% used to construct a larger tree. For example, in:
+%% ```Bar = {bar, 42},
+%%    Foo = ?Q("{foo, _@Bar@@}")'''
+%% (where Bar is just some term, not a syntax tree) the result `Foo' will be a
+%% syntax tree representing `{foo, {bar, 42}}'. This avoids the need for
+%% temporary variables in order to inject data, as in
+%% ```TmpBar = erl_syntax:abstract(Bar),
+%%    Foo = ?Q("{foo, _@TmpBar}")'''
+%%
+%% If the context requires an integer rather than a variable, an atom, or a
+%% string, you cannot use the uppercase convention to mark an automatic
+%% metavariable. Instead, if the integer (without the `909'-prefix and
+%% lift/glob markers) ends in a `9', the integer will become an Erlang-level
+%% variable prefixed with `Q', and if it ends with `99' it will also be
+%% automatically abstracted. For example, the following will increment the
+%% arity of the exported function f:
+%% ```case Form of
+%%        ?Q("-export([f/90919]).") ->
+%%            Q2 = erl_syntax:concrete(Q1) + 1,
+%%            ?Q("-export([f/909299]).");
+%%        ...'''
+%%
+%% == When to use the various forms of metavariables ==
+%%
+%% Merl can only parse a fragment of text if it follows the basic syntactical
+%% rules of Erlang. In most places, a normal Erlang variable can be used as
+%% metavariable, for example:
+%% ```?Q("f(_@Arg)") = Expr'''
+%% but if you want to match on something like the name of a function, you have
+%% to use an atom as metavariable:
+%% ```?Q("'@Name'() -> _@@@@_." = Function'''
+%% (note the anonymous glob variable `_@@@@_' to ignore the function body).
+%%
+%% In some contexts, only a string or an integer is allowed. For example, the
+%% directive `-file(Name, Line)' requires that `Name' is a string literal and
+%% `Line' an integer literal:
+%%
+%% ```?Q("-file(\"'@File\", 9090).") = ?Q("-file(\"foo.erl\", 42).")).'''
+%% This will extract the string literal `"foo.erl"' into the variable `Foo'.
+%% Note the use of the anonymous variable `9090' to ignore the line number. To
+%% match and also bind a metavariable that must be an integer literal, we can
+%% use the convention of ending the integer with a 9, turning it into a
+%% Q-prefixed variable on the Erlang level (see the previous section).
+%%
+%% === Globs ===
+%%
+%% Whenever you want to match out a number of elements in a sequence (zero or
+%% more) rather than a fixed set of elements, you need to use a glob. For
+%% example:
+%% ```?Q("{_@@@@Elements}") = ?Q({a, b, c})'''
+%% will bind Elements to the list of individual syntax trees representing the
+%% atoms `a', `b', and `c'. This can also be used with static prefix and suffix
+%% elements in the sequence. For example:
+%% ```?Q("{a, b, _@@@@Elements}") = ?Q({a, b, c, d})'''
+%% will bind Elements to the list of the `c' and `d' subtrees, and
+%% ```?Q("{_@@@@Elements, c, d}") = ?Q({a, b, c, d})'''
+%% will bind Elements to the list of the `a' and `b' subtrees. You can even use
+%% plain metavariables in the prefix or suffix:
+%% ```?Q("{_@First, _@@@@Rest}") = ?Q({a, b, c})'''
+%% or
+%% ```?Q("{_@@@@_, _@Last}") = ?Q({a, b, c})'''
+%% (ignoring all but the last element). You cannot however have two globs as
+%% part of the same sequence.
+%%
+%% === Lifted metavariables ===
+%%
+%% In some cases, the Erlang syntax rules make it impossible to place a
+%% metavariable directly where you would like it. For example, you cannot
+%% write:
+%% ```?Q("-export([_@@@@Name]).")'''
+%% to match out all name/arity pairs in the export list, or to insert a list of
+%% exports in a declaration, because the Erlang parser only allows elements on
+%% the form `A/I' (where `A' is an atom and `I' an integer) in the export list.
+%% A variable like the above is not allowed, but neither is a single atom or
+%% integer, so `` '@@@@Name' '' or `909919' wouldn't work either.
+%%
+%% What you have to do in such cases is to write your metavariable in a
+%% syntactically valid position, and use lifting markers to denote where it
+%% should really apply, as in:
+%% ```?Q("-export(['@@_@@Name'/0]).")'''
+%% This causes the variable to be lifted (after parsing) to the next higher
+%% level in the syntax tree, replacing that entire subtree. In this case, the
+%% `` '@@_@@Name'/0 '' will be replaced with `` '@@@@Name' '', and the ``/0''
+%% part was just used as dummy notation and will be discarded.
+%%
+%% You may even need to apply lifting more than once. To match the entire
+%% export list as a single syntax tree, you can write:
+%% ```?Q("-export(['@@__Name'/0]).")'''
+%% using two underscores, but with no glob marker this time. This will make the
+%% entire ``['@@__Name'/0]'' part be replaced with `` '@@Name' ''.
+%%
+%% Sometimes, the tree structure of a code fragment isn't very obvious, and
+%% parts of the structure may be invisible when printed as source code. For
+%% instance, a simple function definition like the following:
+%% ```zero() -> 0.'''
+%% consists of the name (the atom `zero'), and a list of clauses containing the
+%% single clause `() -> 0'. The clause consists of an argument list (empty), a
+%% guard (empty), and a body (which is always a list of expressions) containing
+%% the single expression `0'. This means that to match out the name and the
+%% list of clauses of any function, you'll need to use a pattern like
+%% ``?Q("'@Name'() -> _@_@Body.")'', using a dummy clause whose body is a glob
+%% lifted one level.
+%%
+%% To visualize the structure of a syntax tree, you can use the function
+%% `merl:show(T)', which prints a summary. For example, entering
+%% ```merl:show(merl:quote("inc(X, Y) when Y > 0 -> X + Y."))'''
+%% in the Erlang shell will print the following (where the `+' signs separate
+%% groups of subtrees on the same level):
+%% ```function: inc(X, Y) when ... -> X + Y.
+%%      atom: inc
+%%      +
+%%      clause: (X, Y) when ... -> X + Y
+%%        variable: X
+%%        variable: Y
+%%        +
+%%        disjunction: Y > 0
+%%          conjunction: Y > 0
+%%            infix_expr: Y > 0
+%%              variable: Y
+%%              +
+%%              operator: >
+%%              +
+%%              integer: 0
+%%        +
+%%        infix_expr: X + Y
+%%          variable: X
+%%          +
+%%          operator: +
+%%          +
+%%          variable: Y'''
+%%
+%% This shows another important non-obvious case: a clause guard, even if it's
+%% as simple as `Y > 0', always consists of a single disjunction of one or more
+%% conjunctions of tests, much like a tuple of tuples. Thus:
+%% <ul>
+%%   <li>``"when _@Guard ->"'' will only match a guard with exactly one
+%%     test</li>
+%%   <li>``"when _@@@@Guard ->"'' will match a guard with one or more
+%%     comma-separated tests (but no semicolons), binding `Guard' to the list
+%%     of tests</li>
+%%   <li>``"when _@_Guard ->"'' will match just like the previous pattern, but
+%%     binds `Guard' to the conjunction subtree</li>
+%%   <li>``"when _@_@Guard ->"'' will match an arbitrary nonempty guard,
+%%     binding `Guard' to the list of conjunction subtrees</li>
+%%   <li>``"when _@__Guard ->"'' will match like the previous pattern, but
+%%     binds `Guard' to the whole disjunction subtree</li>
+%%   <li>and finally, ``"when _@__@Guard ->"'' will match any clause,
+%%     binding `Guard' to `[]' if the guard is empty and to `[Disjunction]'
+%%     otherwise</li>
+%% </ul>
+%%
+%% Thus, the following pattern matches all possible clauses:
+%% ```"(_@@Args) when _@__@Guard -> _@@Body"'''

-    <title>TEST SUITE LINE NUMBERS</title>
-    <p>If a test case fails, the test server can report the exact line
-      number at which it failed. There are two ways of doing this,
-      either by using the <c>line</c> macro or by using the
-      <c>test_server_line</c> parse transform.
-      </p>
-    <p>The <c>line</c> macro is described under TEST SUITE SUPPORT
-      MACROS below. The <c>line</c> macro will only report the last line
-      executed when a test case failed.
-      </p>
-    <p>The <c>test_server_line</c> parse transform is activated by
-      including the headerfile <c>test_server_line.hrl</c> in the test
-      suite. When doing this, it is important that the
-      <c>test_server_line</c> module is in the code path of the erlang
-      node compiling the test suite. The parse transform will report a
-      history of a maximum of 10 lines when a test case
-      fails. Consecutive lines in the same function are not shown.
-      </p>
-    <p>The attribute <c>-no_lines(FuncList).</c> can be used in the
-      test suite to exclude specific functions from the parse
-      transform. This is necessary e.g. for functions that are executed
-      on old (i.e. &lt;R10B) OTP releases. <c>FuncList = [{Func,Arity}]</c>.
-      </p>
-    <p>If both the <c>line</c> macro and the parse transform is used in
-      the same module, the parse transform will overrule the macro.

     <title>TEST SUITE SUPPORT MACROS</title>
     <p>There are some macros defined in the <c>test_server.hrl</c>
       that are quite useful for test suite programmers:
       </p>
-    <p>The <em>line</em> macro, is quite
-      essential when writing test cases. It tells the test server
-      exactly what line of code that is being executed, so that it can
-      report this line back if the test case fails. Use this macro at
-      the beginning of every test case line of code.
-      </p>
     <p>The <em>config</em> macro, is used to
       retrieve information from the <c>Config</c> variable sent to all
       test cases. It is used with two arguments, where the first is the

-    <p>If the <c>line_trace</c> macro is defined, you will get a

-      which line is currently being executed, and when the line was

-      </p>
-    <p>The <c>line_trace</c> macro can also be used together with the

+    <p>In the past, ERTS did not produce line numbers when generating
