<p>The location information SHOULD be communicated by means of &xep0060; or the subset of publish-subscribe specified in &xep0163;. Because location information is not pure presence information and can change independently of the user's availability, it SHOULD NOT be provided as an extension to &PRESENCE;, although an application MAY do so if necessary.</p>
<section2 topic='Entity publishes location via pubsub' anchor='usecases-pubsub'>
<p>In order to provide information about one's location, the publishing entity should use the pubsub protocol (the following examples show use of the publish-subscribe subset specified in <cite>XEP-0163</cite>).</p>

<p>If an entity has generated or been issued a random resource identifier but it wishes to inform all of the entities on its roster about its location, the entity MAY publish a presence stanza that includes a location. It is RECOMMENDED to include only the &lt;description/&gt; element, since full locations SHOULD be published using PEP in order to save bandwidth and ensure appropriate access control.</p>
