-      <p>When a Jabber entity wishes to subscribe to a node, it sends a subscription request to the pubsub service. The subscription request is an IQ-set where the &lt;pubsub/&gt; element contains one and only one &lt;subscribe/&gt; element. The &lt;subscribe/&gt; element MUST possess a 'node' attribute specifying the node to which the entity wishes to subscribe. The &lt;subscribe/&gt; element MUST also possess a 'jid' attribute specifying the exact XMPP address to be used as the subscribed JID -- often a bare JID (&BAREJID;) or full JID (&FULLJID;), although JIDs of the form &DOMAIN; or &DOMAINRES; may subscribe as well.</p>
