I think the problem in the original text is the use of the word 
'consumed' which implies removal, a forwarding intermediary should 
never be playing the ultimateReceiver role so the header block should 
never be removed until the message reaches the ultimate receiver.

Active intermediaries can always change the message "in ways not 
described in the inbound SOAP message" so its questionable that adding 
a special header block would help.
