<p>Implementations of pubsub MAY deliver event notifications only when the subscriber is online. In these cases, the option may be a node configuration option as shown in the examples above. To facilitate this, the pubsub service needs to subscribe to the subscriber's presence and check the subscriber's current presence information before sending any event notifications (as described in <cite>RFC 3921</cite>). Presence subscriptions MUST be based on the subscribed JID.</p>
</section2>
<section2 topic='IQ Notifications' anchor='impl-iqnotify'>
<p>If the pubsub service supports presence-based delivery and a node is configured to enable such delivery, the service MAY offer a value of "iq" for the "pubsub#notification_type" node configuration option. If this value is chosen, the service shall deliver notifications in XMPP IQ stanzas instead of in XMPP message stanzas. Because IQ stanzas are addressed to full JIDs &LOCALFULL;, if the service does not know the full JID of a given subscriber then it SHOULD NOT send an event notification at all (just as it would not for presence-based delivery via &MESSAGE; stanzas). The IQ stanza containing an event notification shall be of type "set", and in accordance with the semantics of the IQ stanza defined in <cite>RFC 3920</cite> the recipient MUST return either an IQ stanza of type "result" or an IQ stanza of type "error". An example follows.</p>

<section2 topic='Not Routing Events to Offline Storage' anchor='impl-offline'>
<p>Sending events to users of existing Jabber servers may force event notifications to be routed to offline storage for later delivery (as described in &xep0160;). This may not always be desirable. The possible ways of preventing this behavior include:</p>
