Okay, now *that* is an argument I can accept.  What I hear you saying  
is that Phil's parser should *not* be making those assumptions.  Is  
that your point?

If so, perhaps what we really need is not so much a refinement of  
XMDP, but a list of the *practical* questions parser writers are  
asking, and clarification of what the "right" answers to those  
questions are. Right?

I'll buy that as a starting hypothesis, but I'd love to see data to  
either confirm/refute that -- in the context of actual  
implementations, of course.
