You're right. For UniqueIDs there may be other requirements, because
they may be stored in external services like catalogues or databases
(e.g. consider the site names, which start in the GOCDB and propagate
all over the place - not trivial to change).

Well, it isn't entirely obvious that StorageEndpoint *can* represent
APs, that was one of my questions ... but in any case for SRM the
protocol endpoints would normally not be published because you don't use
them directly, you're supposed to ask the SRM for a TURL. However, you
would still like to have the list of protocol types which are supported.
Also there could be other complications, for example an SE might have a
gridftp server for reasons other than it being an accessprotocol (e.g.
the CE currently has one to allow RTE tags to be published ...)
