<p>The &lt;publish-options/&gt; element SHOULD contain a data form (see <cite>XEP-0004</cite>), whose FORM_TYPE SHOULD be "http://jabber.org/protocol/pubsub#publish-options" (see <cite>XEP-0068</cite>).</p>
<p>How the fields are to be handled is up to the the pubsub service, which in the language of XEP-0004 functions as a form-processing entity.</p>
<p>For example, the service may treat the field as a precondition, in which case the service should proceed as follows:</p>
<p>The &lt;publish-options/&gt; element MUST contain a data form (see <cite>XEP-0004</cite>), whose FORM_TYPE MUST be "http://jabber.org/protocol/pubsub#publish-options" (see <cite>XEP-0068</cite>).</p>
<p>Fields and their behaviour MUST be registered with the XMPP Registrar. Each field MUST specify whether it defines METADATA to be attached to the item, a per-item OVERRIDE of the node configuration, or a PRECONDITION to be checked against the node configuration. A pubsub service advertising support for publishing options MUST reject publications with unknown fields.</p>
<p>A field defined as a precondition MUST be processed as follows:</p>
<ol>
<li>If the node exists and the precondition is not met, then the publish shall fail with a &conflict; error condition and a pubsub-specific condition of &lt;precondition-not-met/&gt;.</li>
<li>If the node exists and the precondition is not met, then the publish MUST fail with a &conflict; error condition and a pubsub-specific condition of &lt;precondition-not-met/&gt;.</li>
<li>If the node exists and the precondition is met, then the publish succeeds.</li>
<li>If the node does not exist and the service supports the "auto-create" feature, then the service shall auto-create the node with default configuration in all respects except those specified in the preconditions, and the publish succeeds.</li>
<li>If the node does not exist and the service does not support the "auto-create" feature, then the publish shall fail.</li>
