Subject: RE: TA agenda Tokyo


  What you state makes no sense.  The architecture document was commissoned
at the
same time as the other documents, and is the document which really has the
ground to cover.  Using your logic, it was a predetermined fact that the TA
would not be complete before the more tightly scoped special interest groups
with their specifications.

  What needs to happen is the other groups, such as TRP, REGREP, BP/CC,
must work with the TA group to align their specifications with what the TA
has done.  Since the TA specification is very young, it stands to reason
the more developed specifications of the sub groups would influence the TA
evolution, but it should not become a puppet of those sub groups as doing so
be a statement of failure of the whole ebXML effort as a whole, that common
sense protocol
was not followed.

The TA document suppose be the (road map) to what is being develop in the
specs the working groups spend 12 month working on, the TA doc suppose to
define the interfaces and interactions between all the components, and if
these working group  are developing their spec according to the scope and
the functionality of exbxml requirements doc, and there are no overlaps or
problems with the integration between the components, they not suppose to
change just because the TA document has larger scope or different
functionality. I know it is not how it should be done, and the TA document
suppose to be the first document and provide the road map for other specs to
follow, but you know as every one else in ebxml know, it is too late for
