Oops, you're right .. but faults are of course different from other
messages in that other messages in a pattern have a 1-1 relationship
with an actual message. Hmm, I guess in general even that may not be
the case.

I see we need more thought/work in this area. Can  we live with a 1-1
relationship for message references to real messages? Otherwise
even that gets messy. 

For faults, I guess I see that a single fault ref can be implemented 
by different app level fault types and there's no way the pattern 
def can take that into account. Given that, I'd be ok with allowing
one to repeat <fault> elements with the same messageReference value
to have the semantic that Roberto indicated. Roberto's syntax pref
is ok too, but I'm a bit concerned with syntactic non-similarity with
