message headers for Ack and Fault ??

Title: message headers for Ack and Fault ??

Could someone remind me why we need an RM:MessageHeader element for Ack and Fault messages?
I could not justify this to our implementor Hamid.
Such headers could not possibly have a meaning for these signals, as
they would have to fully relate to a business response that we want to be reliable, in case
of request-response pattern, or more generally in case these signals piggy-back on business messages.
