Re: [ebxml-cppa-negot] Negotiation Process diagram - Initial Draft

Kevin,

This is a great start.  I'll let you know if I have any questions about the
figure.

As to your questions:

1. It is probably reasonal to decide at least as a stake in the ground that
the being-inquired party supplies the NCPA.  However I believe that is an
arbitrary decision and could just as easily be the inquiring party.  What
we don't want is for both parties to supply NCPAs because then we have to
resolve that race.

2. Yes, since the CPA template implies  (mostly) take-it-or-leave-it
situation, it should come from one party.  Again, it's arbitrary which one
but we want to avoid a race condition.  I will say that it is the
being-inquired party that supplies the CPA template.  I think it's OK for
party to publish both a CPP and a CPA template but then there is the
problem of who finds which one.  A better solution may be that a party
publishes only a CPP but after being contacted may then send a CPA
template.

Both of these are good food for discussion at the F2F.

Regards,
Marty
