how about using a single default URI, that simply means
there is absolutely no semantics attached to this value:
(I don't like falling back on pseudo-roles like
Requester / Responder, that may actually conflict with real role
values...)

I notice that Role is still not a
required element in the ebMS header.
I would like the schema to require
its use as unnecessary interoperability problems can be avoided by requiring the
element.
Also, when ebMS is used with CPPA
(and when CPPA is connected with BPSS), it promotes integration by including the
Role element.
If the CPPA and BPSS are not used,
it is easy to just default Role to something like Requester or
Responder.
