I buy that. However, while the base SOAP 1.2 processing model doesn't
address this directly I think it is important to enable this kind of
scenario as part of SOAP based systems. The term *sender* wasn't in this
case intended to be seen as a raw SOAP node but rather a part of an
application with a notion of the intended or ultimate destination of the
message.
