+
+<description>
+
+<p>
+Incoming Diameter messages are decoded from binary() before being
+communicated to &man_app; callbacks.
+Similarly, outgoing Diameter messages are encoded into binary() before
+being passed to the appropriate &man_transport; module for
+transmission.
+The functions in this module implement this encode/decode.</p>
+
+<note>
+<p>
+Calls to this module are made by diameter itself as a consequence of
+configuration passed to &mod_start_service;.
+The encode/decode functions may also be useful for other purposes (eg.
+test) but the diameter user does not need to call them explicitly when
+sending and receiving messages using &mod_call; and the callback
+interface documented in &man_app;.</p>
+</note>
+
+<p>
+The &header; and &packet; records below
+are defined in diameter.hrl, which can be included as follows.</p>
+
+<pre>
+-include_lib("diameter/include/diameter.hrl").
+</pre>
+
+<p>
+Application-specific records are definied in the hrl
+files resulting from dictionary file compilation.</p>

+<item>
+<p>
+The representation of a Diameter message as passed to
+&mod_call; or returned from a &app_handle_request; callback.
+The record representation is as outlined in &records;:
+a message as defined in a dictionary file is encoded as a record with
+one field for each component AVP.
+Equivalently, a message can also be encoded as a list whose head is
+the atom-valued message name (as specified in the relevant dictionary
+file) and whose tail is a list of <c>{AvpName, AvpValue}</c> pairs.</p>
+
+<p>
+Another list-valued representation allows a message to be specified
+as a list whose head is a &header; and whose tail is an &avp; list.
+This representation is used by diameter itself when relaying requests
+as directed by the return value of a &app_handle_request; callback.
+It differs from the other other two in that it bypasses the checks for
+messages that do not agree with their definitions in the dictionary in
+question: messages are sent exactly as specified.</p>
+
+</item>
+
+<marker id="packet"/>
+
+<tag><c>packet() = #diameter_packet{}</c></tag>
+<item>
+<p>
+A container for incoming and outgoing Diameter messages.
+Fields have the following types.</p>
+
+<taglist>
+
+<tag><c>header = &header; | undefined</c></tag>
+<item>
+<p>
+The Diameter header of the message.
+Can be (and typically should be) <c>undefined</c> for an outgoing
+message in a non-relay application, in which case diameter provides
+appropriate values.</p>
+</item>
+
+<tag><c>avps = [&avp;] | undefined</c></tag>
+<item>
+<p>
+The AVPs of the message.
+Ignored for an outgoing message if the <c>msg</c> field is set to a
+value other than <c>undefined</c>.</p>
+</item>
+
+<tag><c>msg = &message; | undefined</c></tag>
+<item>
+<p>
+The incoming/outgoing message.
+For an incoming message, a record if the message can be
+decoded in a non-relay application, <c>undefined</c> otherwise.
+For an outgoing message, setting a <c>[&header; | &avp;]</c> list is
+equivalent to setting the <c>header</c> and <c>avps</c> fields to the
+corresponding values.</p>
+
+<warning>
+<p>
+A record-valued <c>msg</c> field does <b>not</b> imply an absence of
+decode errors.
+The <c>errors</c> field should also be examined.</p>
+</warning>
+
+</item>
+
+<tag><c>bin = binary()</c></tag>
+<item>
+<p>
+The incoming message prior to encode or the outgoing message after
+encode.</p>
+</item>
+
+<tag><c>errors = [5000..5999 | {5000..5999, avp()}]</c></tag>
+<item>
+<p>
+Errors detected at decode of an incoming message, as identified by
+a corresponding 5xxx series Result-Code (Permanent Failures).
+For an incoming request, these should be used to formulate an
+appropriate answer as documented for the &app_handle_request;
+callback in &man_app;.
+For an incoming answer, the &mod_application_opt;
+<c>answer_errors</c> determines the behaviour.</p>
+</item>
+
+<tag><c>transport_data = term()</c></tag>
+<item>
+<p>
+An arbitrary term of meaning only to the transport process in
+question, as documented in &man_transport;.</p>
