It certainly may be- and if you're using WS-Addressing you can
deal with that by putting the message ID in the ReplyTo EPR .. that
way it'll be there when the reply comes and you'll know what
its about. (There's the RelatesTo property too.) If another 
addressing mechanism doesn't support such a feature then its
pretty much busted IMO.

In any case, this is all hooks we're putting to avoid a political
problem at this time IMO. For the success of the Web services
platform, it is ABSOLUTELY critical that there be one and only
one addressing/referenceing/whatchamacallit standard. Until we
get there everything is and will be broken.

As far as WSDL is concerned, if we can create a solution that can
work with that standard then we're in business. In the meantime, 
it better work with the current bevvy of candidates too.
