This looks good, except that I think that my comment was mostly addressed at the first sentence. I'd prefer:
Some performing the Location _Server_ role are designed only to
provide Targets with their own locations (as opposed to
distributing a Target's location to others). ...
Reason: I'm a nasty pedant.
Or: The Location Server is the only role that provides location to any other entity. Consider the possibility that the entity providing location information did not generate it.
(nit: The first paragraph could be three, given that it makes three distinct statements.)
