The other relevant bit of info is that the attribute @xml:id will 
always be recognized by a 2.0 processor as equivalent to type ID, for 
purposes of id().

I concur with David's and Mike's advice to prefer key() -- cleaner 
layering -- but there are times when you save bacon by using @xml:id.

Cheers,
Wendell
