Mike,
While I agree there's value in doing this for ebXML users and the community at
large, I am concerned about the timing and scope.  Where do we stop with the
analysis of ebXML and WSA layering?  Do we dig into BPSS and choreography as
well?  If we head in this direction we should carefully define and bound the
exercise, or we'll get into the weeds and slow down our work on the
architecture.

I don't believe now is the right time to start this.  Our document is in
transition and we should get the core parts we've identified solid before we
branch off onto something else.  Can we put it on the list and prioritize?

Thanks,
Colleen
