RE: [ebxml-msg] Re: Comments on the 1.09 about signed AcknowledgementMessage

[David Fischer <david@drummondgroup.com>]

A signed message is a message with a ds:Signature element.  An Acknowledgment
Message is one with an Acknowledgment element.  A signed Acknowledgment message
would be one with both.  There is no need for a ds:Signature element inside the
Acknowledgment element.

The spec already says that a signed Acknowledgment Message MUST include a
ds:Reference element within the Acknowledgment element 7.3.2.6 and there is a
special section about signing intermediate Acknowledgments 11.1.4.

Regards,

David.
