Close :) Processing by an intermediary may NOT result in a message being
forwarded. In a two-way message exchange pattern, a cache may determine
that it can deal with the message and short-circuit the message path
like for example an HTTP cache does. In this case, the cache acts on
behalf of the ultimate destination without actually being the ultimate
destination.

There are also cases where a message path fails and an intermediary
returns a fault. In this case, it *does* act as an initial sender of the
fault message although it doesn't act as the ultimate destination of the
incoming message (this is what the faultactor is for). Maybe the text in
section 2.5 [1] covers this already:

"If the SOAP node is a SOAP intermediary, the SOAP message pattern and
results of processing (e.g. no fault generated) MAY require that the
SOAP message be sent further along the SOAP message path."

Sorry if I have missed this but is this intended for the terminology
section? Does it need to be repeated, or?

Thanks!

Henrik
