I agree that the poll request can be used to obtain status infomation
for reliable messages sent using any reply pattern.

The point I am making is that the poll request is always (by definition
and design) mapped to an underlying request/response protocol.

Thus there is no problem distinguishing a delayed callback response
(which is always on an underlying request) from a poll response
(which is always on a underlying response).

 As I mentioned earlier, poll response need to be  on
the underlying response.
 The requirement we had was that poll request be sent on a separate
  transaction/connection than that of the original reliable message.
Requiring
  it to be on the same response is an un-necessary implementation
restriction.

 Also, when the ACK or Fault comes to the RMP/SOAP processing later,
 it  will be (most likely) agnostic to that fact that it was carried thru' a underlying
 request or underlying response.
