<p>&xmppcore; specifies that an XMPP error stanza may include a child element qualified by an XML namespace other than 'urn:ietf:params:xml:ns:xmpp-stanzas'. This enables any XMPP protocol extension to define its own application-specific error conditions, such as the following:</p>
|
|
<example caption='An Application-Specific Error Condition (invalid-jid)'><![CDATA[
|
|
<iq type='error' from='pubsub.shakespeare.lit' to='francisco@denmark.lit/barracks' id='sub1'>
|
|
<pubsub xmlns='http://jabber.org/protocol/pubsub'>
|
|
<subscribe node='blogs/princely_musings' jid='bernardo@denmark.lit'/>
|
|
</pubsub>
|
|
<error type='modify'>
|
|
<bad-request xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/>
|
|
<invalid-jid xmlns='http://jabber.org/protocol/pubsub#errors'/>
|
|
</error>
|
|
</iq>
|
|
]]></example>
|
|
<p>Although the inclusion of application-specific error conditions introduces a great deal of flexibility, it may also lead to confusion regarding possible conditions. Therefore, this document defines a registry of application-specific error conditions, to be maintained by the ®ISTRAR;. In addition, this document registers a namespace of 'urn:xmpp:errors' as a fallback namespace for generalized error conditions that are not specific to a particular protocol (e.g., <stanza-too-big/> as a particular form of the ¬acceptable; condition).</p>

<section2 topic='Application-Specific Error Conditions Registry' anchor='registrar-conditions'>
|
|
<p>The XMPP Registrar maintains a registry of application-specific error conditions (see &APPERRORS;).</p>
|
|
<p>All application-specific error conditions that are defined in XMPP Extension Protocol specifications MUST be included in this registry. Application-specific error conditions that are defined outside of the XMPP Standards Foundation's standards process (see &xep0001;) MAY be included in this registry, but it is not required for them to be so registered.</p>
