Subject: RE: [business-transaction] Groups - BT-TC-FAQ.txt uploaded

Hi Doug,
Firstly thanks for the comments.

Your are right this document is slightly out of date.  In early August
OASIS solicited the TC chairs for FAQ documents.  This is the document
that I sent them at that point.  There was some problem getting it up on
the TC page so I resent the document to OASIS staff and made it visible
as a TC document too.

You do raise a larger point.  This should be a document that has been
reviewed and voted by the TC.  I would like to have something up on
the web page,  perhaps this document with edits?  I am happy to make
those edits and circulate a draft for comment.

More comments embedded in-line below.

Right, absolutely.  I have had emails requesting that WS-C+T (or AT),
WS-CAF, and BPSS be called out.  Any others?

It was discussed at both the Liberty Corner face-to-face and the
Newcastle face-to-face.  There was concensus, though not 100%
agreement, that this was an important value add.

Ok, it was meant to touch on areas of difference between BTP and some
of the other work that was out at the time.

Right, it is an apples to oranges comparison.

I asked this question directly of Karl Best and the reply was that we
are free to continue to use the name as it was adopted or we can
change it to conform to the new form, up to us.
