<p>Even though a client might be available (as stated in the most recent presence stanza), the user this client belongs to might not be focused on the client currently. &xep0132; defines a method for a physical test of user presence. Since this requires special hardware that cannot be assumed to be available, this XEP defines a software-only implementation where no direct feedback is expected. This feature is known as 'nudge' or 'buzz' in some non-XMPP IM protocols.</p>

<li>Messages containing an attention extension SHOULD use the headline message type to avoid offline storage.</li>
