We already cover acknowledgements normatively, but if we need them in 
the invariants, I think it should simply say:

When the RM Destination receives an AckRequest header block, it MUST 
issue a Sequence Acknowledgement header block that MUST
include one or more AcknowledgementRange child elements that contain, in 
their collective ranges, the message number of every message accepted by 
the RM Destination. The RM
Destination MUST exclude, in the AcknowledgementRange elements, the 
message numbers of any messages it has not accepted.
