Hi all,

	XMLP Service Consumer could be more descriptive. And of course the
relationship is many to many.

|Where I was coming from is that gradually the notion of a

|this it also sets the boundary on what needs to be defined in the specs. we
|The recent rewording around handler has removed references to "XML protocol

|we loose the notion of a thing that 'uses' the XMLP layer and/or some
|(logical) container for a collection of handlers at a node. The suggested
|revisions to the diagram were an attempt to reflect the recent glossary
|Personnally I would prefer not to loose the concept of a user/client of the
|XMLP layer and I was reasonably comfortable with it as a container for a
|bunch of handlers. If "XMLP Application" is not a good terms for that
|concept, and there seems some reluctance to accept the term, then
|lets think
|of a new name for it. We've had:
|	Layer Client
|	XMLP Service user
|	XMLP Application
|My personal favorite remains Layer Client... but it seemed to cause
