Good beginning, but I dislike all examples :-)

In general, I think that sending along a start time for presence, and extended
presence sent using pubsub with an ItemID of 'current' makes little sense. We
are dealing with a near-realtime communication medium. I can think of two

 - Notifications that are delivered some time after the actual publish, but
   this would be something that could be changed by resp. the server and pubsub
   service. Of course, jabber:x:delay comes into mind here as well.

 - Automatic away/xa. One could use timeperiod for conveying the beginning of
   inactivity (which is before sending the presence!).

For pubsub, I think I'd like it better if this extension would be a direct
child of the <item/>.
