I think that would be valid, but useless in the FOAF world:

| If a user-agent received a telephony URL with a local number
| in it, it MUST make sure that it knows the context in which
| the local phone number is to be processed, or else the
| number MUST NOT be used.

So since we can't know the context from the triple level, we can't use it, I
think global numbers are the only useful ones to use.
