I'm feeling dense.  Can you show an example of instance having at least 
one element that would match more than one of the wildcards?   I think 
that's what you have to demonstrate to show that this violates UPA, given 
the new semantics for wildcard matching in Schema 1.1.   What am I 
missing?  I don't see why this violates UPC.
