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.

David.
