So when signed attribute of AckRequired in original message is set to
true, the Acknowledgement Message to the original message MUST have
ds:Signature element in addition to Acknowledgment element? But there is
not such description in the specification. Section in v1.09 just
says that: Persistent Signed Receipt
    An ebXML Message that has been digitally signed MAY be acknowledged
    with an Acknowledgment Message that itself is digitally signed in
    the manner described in the previous section. The Acknowledgment
    Message MUST contain a ds:Reference element consistent with that
    contained in the ds:Signature element of the original message.

This section does not include any description about relationship between
original message's signed attribute of AckRequired and ds:Signature of
Acknowledgment Message.

The team "signed message" you mentions does not appear in the
specification. The audience of the specification will not understand
that signed Acknowledgment Message has ds:Signature element.

And also as Doug Bunting pointed out in
in detail, description about ds:Reference in the section seems
not clear.
