Sure, it's between the initial sender and the specified ultimate
recipient.

Right.

"ultimate" is a deceptive word in the gateway case.  I believe it refers
to the the ultimate recipient as specified by the initial sender.  This
is consistent with SOAP 1.2's use of the word, AFAICT.  It also relates
to issue #2;

and to an even more profound issue about whether a SOAP envelope is
necessarily a message.  But I won't raise that one. 8-)
