Overall, I like this a lot.  Thank you.  I suspect we will want to play 
around with layout and typography, perhaps doing some form of tables, but 
that can come later. 

A few other comments:  I think we need to follow through on some other 
implications for this to be coherent.  Specifically, because this 
addresses only the abstract Envelope section, a naive reader might wonder 
where the <...> went.  After all, most SOAP messages we've seen actually 
do have <..>. 

I think many of us agree that the answer will be found when we describe 
the way bindings work:  any SOAP envelope Infoset necessarily has a 
representation as serialized, well formed XML.  So, I expect that when the 
dust settles, the responsibility of a transport binding will be (roughly) 
to move the envelope Infoset to the next point in the message path, and to 
reconstruct it there.  The binding corresponding to the current SOAP v 1.1 
HTTP binding will indeed use the standard serialization in well formed 
XML: it will have the angle brackets that everyone expects.  Indeed, its 
messages may be nearly indistinguishable from those used today for SOAP 
v1.1.  Lots of other bindings will make the same choice, but others such 
as those that do compression will have wire formats that use other forms 
for the Infoset.

I think that those of us who are enthusiastic about the Infoset 
formulation roughly agree on the above.  I am only pointing out that, 
without the discussion of bindings, readers may be confused.  In summary, 
I really like where this is going, but I don't think it quite stands alone 
yet.  Gudge:  thanks so much for moving this ahead.
