Hi all, Would anybody be able to confirm that it is the intention of the MSS 2.0 specification to allow multiple Acknowlegdment elements with the same actor URI on a single ebXML message? (something of a 'bulk acknowledgment' message). The schema allows it, the 'interaction' rules allow it, although the spec wording always refers to Acknowledgment elements in a singular sense when discussing inclusion in a message. Thanks and Best Regards, Dave Elliot XML Global Technologies
