The 'rel' says only "this is the kind of place where you can receive
notifications about changes to the resource". That doesn't say *how* you
receive those notifications. If the URI is sip:foo then perhaps you need
to poll. If it's xmpp:bar then perhaps you receive pushes. But the "how"
doesn't change the fact that this is where you can get notifications.
