<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 SHOULD 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;.</p>

<p>A service MAY enable entities to subscribe to nodes and apply a filter to notifications (e.g., keyword matching such as "send me all news entries from Slashdot that match the term 'Jabber'"). Such a content-based service SHOULD allow an entity to subscribe more than once to the same node and, if so, MUST use subscription identifiers (SubIDs) to distinguish between multiple subscriptions. In order to prevent collisions, a service that supports content-based subscriptions using SubIDs SHOULD generate SubIDs on behalf of subscribers rather than allowing subscribers to set their own SubIDs. <note>Another way to implement content-based subscriptions is to host one node per keyword or other filter; however, this is likely to require an extremely large number of nodes.</note></p>

<p>Content-based services SHOULD use subscription options to specify the filter(s) to be applied. Because there many possible filtering mechanisms (many of which may be application-specific), this document does not define any such method. However, filtering mechanisms may be defined in separate specifications.</p>
