Hi Martin,

Just a question really. In a scenario that employs intermediaries, what are
our expectations of the value carried in a SOAPAction header on each hop in
the path?

a)  the SOAPAction header to carries the same 
    value on each hop down the path? 

    Either fix or, as you suggest, a value dervied 
    from the uri of the recipient and the 
    fully qualified name of the first 
    child of the body.

b)  least the uri part of the SOAPAction uriref 
    (before the #) to be based on the URI of 
    the intermediary. 

    The part after the # might be derived as 
    in a) or might be derived from the fully 
    qualified name of some notion of a principal 
    header targetted at that intermediary?

c)  some other mechanism....
