RE: [ebxml-msg] Can an MSH send a sync ack and then an async response?

[Cliff Collins <collinsc@sybase.com>]

Doesn't this conflict with the MS 2.0 spec and indirectly change the
functionality of a MSH without the MS team voting on it?

MS Lines 1632-1643 (section 7.4.7) would be in conflict with the CPA 1.1/2.0
and would need to change.
