I think the above may be confusing. Someone may take (perhaps it's just
me) the above to mean that if a new message-based protocol shouldn't use
wsa:action just in case another protocol, with which the new protocol
has to be composable, may use it. That means that ALL protocols should
not use wsa:action. If there was a wsa:action per actor/role then that
wouldn't be a problem. Unless wsa:action is meant to be consumed only by
the ultimateReceiver?

Also, while reading the semantics of wsa:action in the latest published
version of the spec, I noticed that it is RECOMMENDED that the value of
wsa:action be related to WSDL constructs. Why does the spec must provide
this recommendation? If wsa:action has clear semantics, there shouldn't
be a need to do that. I think it should be the other way around. The
WSDL spec should say that the value for its constructs become values for
wsa:action. What if there was another WS description language in the
block? (I just happen to know that a proposal for one is coming :-)
