Somehow, we don't seem to have any category element in the 
format-draft.  Huh?  It's in RSS2 and it's widely deployed, although it 
hasn't been all that useful.  Also I note that the protocol design team 
is worrying about querying and defining categories.  I don't see 
anything wrong with RSS2's category element, so I've proposed something 
along the same lines:
