If you do not distinguish request/response, we cannot properly process
mustUnderstand attriubte.
There were two approaches:
1. The architecture knows the distinction
2. The architecture does not know the distinction.  Rather some specific
handlers for checking
mustUnderstand are placed properly somewhere in the chain.
BTW, is mustUnderstand processing performed in the current Axis?

I think the biggest reason people wanted the split was
because we envisioned a need to be able to get access
to both the incoming and outgoing messages at the same
time.  If we had a single message, and a handler changed
it (ie. removed a header) then that header would no longer
be available to subsequent handlers.  An argument can be
made that maybe they shouldn't be available - or if we went
with a single message then we could just stick the original
message in the 'bag' in the message context.
If I remember correctly, we never really had a "formal" vote
it just sort of evolved into the current state.

Why is the request/response distinction important again?
