ISSUE 2 - Callback support over the Web Service binding

["Michael Rowley" <mrowley@bea.com>]

One problem with using WS-Addressing wsa:ReplyTo is that it is usually
used to send the response message of a request/response pair.  I don't
think that WS-Address forbids its use for subsequent messages
(callbacks), but it would at least be unconventional.

However, if we can't use wsa:ReplyTo, that would seem to imply that we
have to devise our own header to use, but that would be getting
dangerously close to inventing a wire-level protocol, which we don't
want to be doing.
