<p>A node owner MUST NOT define more than one of these options.</p>
<p>An example is shown below.</p>
<p>Interoperability note: As of March 2023, the value of "owner" is not widely supported in generic implementations, and clients may choose to avoid it. In contrast, the value of "none" was not specified in previous versions of this document but has been added retrospectively due to implementation support. Therefore, the primary use of the 'pubsub#itemreply' option is to allow node owners to determine whether the server will <link url='#publisher-publish-success-publisher'>include a 'publisher' attribute in items or not</link>.</p>
<p>The JID associated with an item is conveyed via the 'publisher' attribute on the &lt;item/&gt; element, as demonstrated in the below example:</p>
