RE: [ebxml-msg] CSD03 for AS4

Replying to this as it was copied in the AS4 draft spec:

I agree with you on the sequence acknowledgments,  but the
ebMS 2.0 receipt actually does seem to support NRR because
an eb2:Acknowledgment includes:

1) The unique identifier of the received message
2) A digest value(s) of the received message (parts)
3) A timestamp when the receipt occurred
4) A signature covering 1, 2 and 4 above

Here is an example (from a test message I generated years
ago) that illustrates (1)-(4):

    <eb:Acknowledgment
eb:version="2.0"soap:actor="urn:oasis:names:tc:ebxml-msg:act
or:toPartyMSH" 
       soap:mustUnderstand="1">

The use of the phrase 'business receipt' in AS4 was to
distinguish the nature of the AS4/ebMS3 receipt as being
sufficient for NRR (non-repuation of receipt).  In this
sense it is very similar to the
RFC3798 Message Disposition Notification response that is
used by AS2 as a business receipt for non-repudiation.  This
receipt in AS4/ebMS3 contains the same information as the
MDN, and thus distinguishes itself from the ebMS2
'acknowledgment' or web services reliable messaging
acknowledgment.
