But William,  you are always critical ;-)

Okay - keeping in mind this is a first draft, I have had several people
(both technical and non technical read this document and they all seemed to
understand the general concepts.  The automated process for establishing ad
hoc trading relationships is very clearly defined (IMHO) however,  if you
are having trouble with specific topics, I would be glad to hear the
shortcomings.  I don't think this document should, in itself be the end all
for explaining ebXML to outside people.  This document is to define the
Technical Architecture.  Rachel's group, Marketing etc., will derive a
document meant for explaining it to the general marketplace.

TPAML is largely the process of Trading partner profiles for discovery.  All
though it is not explicity mentioned,  I believe that TPAML (and eCo) are
invaluable for the discovery of trading partner methods.
The establishment of ad hoc trading relationships is defined in section 4
and a process flow has been documented.

It is clearly documented that the Registry and Repository are the heart of
ebXML.  The system won't work without this critical piece.  Yes - we may
have gone overboard with the details of Reg Rep and we will wait for Scott's

Our goal is not to do a comparison between ebXML and EDIFACT (or any other
data standard).  We have clearly documented what ebXML has to offer that
EDIFACT and other infrastructures can't offer.  If someone wants to compare,
they have the freedom to do so.  I'm sure there will be lots of opinions.  I
just hope they come from people who understand the architecture.

I am Out of the office now for about four hours.  I will answer more later.
Thank you for your comments.  They will be taken into account.
