Service/Server description, discovery, and registration is a separate
functionality. While it certainly is an important and interesting area
and should be mentioned in the overall architecture/scenario
document(s), the requirements and the development of such is not in
scope of the current OPES charter.
You might also want to check activities going on in the 'webi' group.
The 'webi' charter has a work item on "intermediary discovery and
description mechanism", which seems somehow related (although my
understanding is that the group is currently focusing on the 'resource
update protocol'). Mark and Ian certainly can jump in here :)
