[ebxml-cppa-negot] discovery of CPA template

[Martin W Sachs <mwsachs@us.ibm.com>]

In our early discussions, we included the possiblity that Party B might
discover Party A's CPA template rather than a CPP.  For this case, the
opening logic  is:

- Party B obtains a copy of Party A's CPA template and NDD.
- Party B fills in its Party ID, communication address, and other details.
- Party B may also modify other aspects of this CPA template that are
indicated as negotiable in the NDD.
- Party B does NOT modify the NDD.
- Party B submits this modified CPA template to Party A as an initial
offer.
- The accompanying negotiation message indicates what Party B has changed
in the CPA template just as in the case of a counter offer.
- The choreography then continues as in the current BPSS instance document,
with Party A making the response to Party B's offer.

Does this scenario require any modifications to the current BPSS instance
document?  I don't think so but I would like other opinions.

Regards,
Marty
