Hi Jean-Jacques.

Thank you for your comments.

I couldn't find a good way to define a concrete WSDL binding. I looked
at the WSDWG documents and couldn't find a definition either. Is there
one somewhere?

I ended up putting:

  The mapping on an abstract description of a message to a concrete

But I am happy to get something better.

I added an editor's note but haven't made the change yet because I am
not totally satisfied by the term "concrete binding".

Again, this is a WSDWG definition. Have these definitions been

We definitely need to talk about this, but my feeling is that this
discussion, and reference, should be in the architecture document, not
in the glossary.

I agree that there should actually be a reference somehow. The MTF has
come up with a state machine for the life cycle of a Web service too,
so I will work on that while working on the management definitions.

In the meantime, I have added an editor's note.

I agree with MarkB that those terms need to be defined in a general
way. I have added a reference to the SOAP definition for intermediary.
It was missing.

Hmmm... sender is really at the message level whereas requester is at
a more conceptual level.

Please see David B's definition.
