This is a good discussion, but I think I disagree with the analysis above. 
 Section 2.7.1 includes what I think is the crucial text [1]:

"A SOAP header block is said to be reinserted if the
processing of that header block determines that the
header block is to be reinserted in the forwarded

This clearly says that the processing rules for a header block can 
determine whether to reinsert, even in the case of a forwarding 
intermediary (I think it's clearly implied that we're talking about 
forwarding intermediaries here.)  We are writing the specification for the 
processing of this header, so we have permission and indeed SHOULD in my 
opinion indicate the rules for reinsertion as a result of such processing. 
 My note was intended to offer two options for such a Representation 
Header processing  specification.  I really don't think that suppying such 
rules makes the node an active intermediary;  on the contrary, I think 
we're doing what the SOAP Rec tells you to do when specifying the 
processing of a header at a forwarding intermediary.  Make sense?
