Fine, but I  have to point to the oxymoron of "extensively internally" 
-- unless I missed it, we are still waiting for a definitive statement 
about the "internal" behaviour of an ODD processor.

Can we think of a user-facing application for <attRef> ? <elementRef> is 
a useful way of pulling  elements into a schema irrespective of their 
class membership, but I don't think the same trick will work for <attRef>.
