I have issues with wsa:ReplyTo as well.  While it would be nice to tell
just from a message whether or not a response it coming back, I think the
MUST requirement is too limiting.  A sender may not know its address, it
may be going through NAT gateways, or whatever.  And if the response is
just coming back, e.g., as an HTTP response, there really is no need to
require this element.
