Dale,
I agree that the Web services approach that you postulate below would
require a rather different approach to negotiation at the SOAP/WSDL level.
I was thinking more along the lines of agreements of the style of the CPA,
i.e. a single XML document that expresses what both parties have agreed to.
Such agreements ought to be amenable to treatment along the lines of our
negotiation specification and in principle, at least, much of our
specification should be usable. I envision such an agreement to be used
within the Web services environment but it would be "outband" of WSDL. It
might be referred to in a WSDL description via one of its extensibility
elements. These agreements might be closer to the business level than WSDL
or CPA and hence get into some of the more complex business negotiation
scenarios, however.
We definitely should hold off on this discussion until we solidify what we
are now doing.
Regards,
Marty

If we do eventually adapt and modify the Negotiation specification to
deal
with web services negotiation, and a CPA is no longer used,
I think even the process specification might need to be revisited.
Perhaps CPAs _could_ be used for web services negotiation (that is one
work
item deferred from 2.0), but then it would still be CPA negotiation.
My point was that if web services groups extend a SOAP features
approach, and combines it with WSDL, they may develop a WSDL++ and
registration approach that differs at least from our negotiation
messages. In
Addition, instead of {proposal, acceptance/counterproposal/rejection},
the flow may be {registration, approval/rejection}. But maybe we should
hold off on this issue until we get the draft ready.

I need to look over Dale's responses in more detail but I have one
immediate rejoinder:
Dale wrote:
"Dale: I am undisturbed by the CPA_ prefix. It at least indicates
that
we are not advocating use of this process outside CPA negotiation."
We should be advocating eventually using as much as possible of this
specification outside CPA negotiation. Web services is an example if it
eventually includes something to negotiate. Except for some element
names,
there is really nothing in the negotiation BPSS instance document that
is
particularly dependent on CPA. However, schedules and workloads being
what
they are, I would not even consider changing the terminology at this
late
date.
Regards,
Marty
