I think it is a good idea to require that a protocol binding describes exactly
how the request-URI can be determined including if it is required to be
carried within the envelope. In many cases, it is obvious where to find it but
there might be more tricky cases like multicast addresses etc.

That there must be a request-URI somewhere I think falls out of building
a protocol in the first place - the purpose of a protocol is exactly to
exchange data and in order to do that one has to describe at least the
destination of the data.

Yes, it is always possible to enforce information to be carried within
the XP envelope by using the optional/mandatory flag indicator that we
have a requirement for.
