Subject: Negotiation comments


	Some comments -

Section  3.3 lifecycle - 
	We should not require nor prohibit the use of third party
negotiation services, IMHO.
	Automated composition - I think that it should be developed enough
to show that the features in the CPP's are rich enough to support the
accurate, consistent formation of a CPA.  This may take the form of
formation rules, or at least a way to express a range of possibilities and
the way to validate that an offer falls within the range.

	Section 3.4 Automated negotiation (business) process
This might be the best way to go.  Then the business could choose to
advertise a take it or leave it single set of values (a la WSDL), and only
if they are willing advertise support for the negotiation process and a more
complicated range of negotiable values, would they need to know about how to
negotiate the values. 

	Section 3.5 Negotiation CPP
Aren't delivery channels abstract enough that the details negotiated in the
transport qualities, and document properties can be viewed as agreed upon,
and the delivery channels can stay unchanged? 

	Section 3.8 Potential Steps in Advertisement, Discovery, and
Should this protocol also support a minimalist non ebXML aware user?  In
that case it might be as simple as 

submission of a CPA (filled out template) to a registry
discovery by a trading partner
do business

Subject: Negotiation: subteam logistics

I have attached the initial version of the negotiation white paper /
requirements document.

At this morning's CPPA conference call, it was decided to hold the
discussions on this document on the CPPA list rather than privately within
the subteam.  Everyone feel free to discuss.  Please prefix the subject
line by the word "Negotiation" or <Negotiation> to allow everyone to do

Extensive comments on specific items in the document may be inserted into a
copy of the document using revision markup.  That copy can then be posted
back to the list.

Please note that the document references the ebXML E-Commerce Patterns, v
1.0 technical report which is available on the ebXML web site.

I also distributed to the subteam a proposal prepared by Duane Nickull a
few months ago.  If anyone else wants a copy, let me know.
