	    <p> Updates to the xml scanner </p> <list> <item>
	    <p>xmerl_scan is now returning xmlComment records in the
	    output.<br/><br/> Functions <c>xmerl_scan:file/2</c> and
	    <c>xmerl_scan:string/2</c> now accepts a new option
	    <c>{comments, Flag}</c> for filtering of comments.<br/>
	    Default (<c>true</c>) is that <c>#xmlComment</c> records
	    are returned from the scanner and this flag should be set
	    to false if one don't want comments in the output. </p>
	    </item> <item> <p>Add <i>default_attrs</i>
	    option<br/><br/> When <i>default_attrs</i> is <c>true</c>
	    any attribute with a default value defined in the doctype
	    but not in the attribute axis of the currently scanned
	    element is added to it. </p> </item> <item> <p>Allow
	    whole documents to be returned<br/><br/> Functions
	    <c>xmerl_scan:file/2</c> and <c>xmerl_scan:string/2</c>
	    now accepts a new option <c>{document, true}</c> to
	    produce a whole document as a <c>xmlDocument</c> record
	    instead of just the root element node.<br/> This option
	    is the only way to get to the top-level comments and
	    processing instructions without hooking through the
	    customization functions. Those nodes are needed to
	    implement [Canonical XML][c14n-xml] support.<br/>

	    field in <c>#xmlDecl</c> record</p></item> <item><p>Fix
	    namespace-conformance constraints<br/><br/> See
	    [Namespaces in XML 1.0 (Third Edition)][1]: The prefix
	    xml is by definition bound to the namespace name
	    http://www.w3.org/XML/1998/namespace. It MAY, but need
	    not, be declared, and MUST NOT be bound to any other
	    namespace name. Other prefixes MUST NOT be bound to this
	    namespace name, and it MUST NOT be declared as the
	    default namespace.<br/> The prefix xmlns is used only to
	    declare namespace bindings and is by definition bound to
	    the namespace name http://www.w3.org/2000/xmlns/. It MUST
	    NOT be declared . Other prefixes MUST NOT be bound to
	    this namespace name, and it MUST NOT be declared as the
	    default namespace. Element names MUST NOT have the prefix
	    xmlns.<br/> In XML documents conforming to this
	    specification, no tag may contain two attributes which
	    have identical names, or have qualified names with the
	    same local part and with prefixes which have been bound
	    to namespace names that are identical.<br/> [1]

	    <p> Updates of xmerl's Xpath functionality. </p> <list>
	    <item><p>Add <c>#xmlPI</c> support to
	    xmerl_xpath:write_node/1</p></item> <item><p>Fix

	    correctly implemented, attributes nodes corresponding to
	    attributes that declare namespaces are ignored.<br/> See
	    [5.3 Attribute Nodes][xpath-5.3]:<br/> There are no
	    attribute nodes corresponding to attributes that declare

        <item>
	    <p> Fixed a schema search bug in xmerl_xsd. </p> <p> A
	    new flag was needed in the xsd_state record so if the
	    state is saved there is an incompatibility and a state
	    conversion is needed. </p>

	    Prevent xmerl from over-normalizing character references
	    in attributes</p>
          <p>
	    Section 3.3.3 of the XML Recommendation gives the rules
	    for attribute-value normalization. One of those rules
	    requires that character references not be re-normalized
	    after being replaced with the referenced characters.

	    <p> The function xmerl_lib:expand_content/1 is mainly for
	    expanding Simple XML, but can also handle xmerl records.
	    This patch fixes an omission that caused expand_content/1
	    to not maintain the parents list when expanding
	    #xmlElement{} records. (Thanks to Ulf Wiger) </p>

	    improperly replaced hex entities by the UTF-8 bytes
	    instead of returning the character, as it does with
	    inline UTF-8 text and decimal entities. (Thanks to Paul

            The SAX parser couldn't handle consecutive documents on
            the same stream. The return values are now changed so
            they return a rest value instead of giving an error about
            "erranous information after the end tag". 
          </p>
          <p>
            This means that
            the functions <c>file/2</c> and <c>stream/2</c> now
            returns <c>{ok, EventState, Rest}</c> when the parsing is
            correct. The rest can then be used as input to a new call
            to <c>xmerl_sax_parse:stream/2</c>. If one know that it's
            just one document the rest value in the result tuple can
            be matched against <c>&lt;&lt;&gt;&gt;</c> or <c>[]</c>
            depending on if the input is in binary form or not.

<section><title>Xmerl 1.2</title>
    <section><title>Improvements and New Features</title>
	<p>
        In xmerl-1.2 we have added the first Beta version of the new 
        SAX parser (module: xmerl_sax_parser), it supports XML 1.0. 
        We call it Beta due to that the validation part is not ready yet and that the 
        parser still has some known limitations (mostly in the DTD area).
        </p>
	<p>
	Known limitations: 
        </p>
        <list type="bulleted">
          <item>the external DTD in the DOCTYPE declaration is handled but other external entities are not supported.</item>
          <item>the general entity values are just checked in the structure after replacement.</item>
          <item>
             parsed entities are supported on markup declaration level (e.g. partly replacement of markup 
             declaration with PEReference is not supported).
          </item>
          <item>conditionalSect in external DTD's are not supported.</item>
          <item>recursive loops in entity declarations are not detected.</item>
        </list>
	<p>	
	 The version is increased from 1.1.12 to 1.2 is due to that the new parser
         is dependent on the Unicode support that was added in OTP R13B. The old xmerl 
         functionality is not changed.
