[Geopriv] held-identity and subjective network views

Section 3.1.1 of held-identity says:
> Subjective views of the network mean that the identifier a requests
> uses to refer to one physical entity could actually apply to a
> different physical entity when used in a different network context.
> Unless an authorized third party requester and LIS operate in the
> same network context, each could have a different subjective view of
> the meaning of the identifier.
> In this case, the third party receives information that is correct
> only within the network context of the LIS. The location information
> provided by the LIS is probably misleading: the requester believes
> that the information relates to a different entity than it was
> generated for.
This notes the potential for misleading location information, but does
not explain that subjective views also create the potential for the
LIS to apply the wrong policy to a given location request. It's sort
of implied, but I think it's worth stating explicitly, because it
creates a problem of equal concern if the LIS doesn't realize it's
dealing with a subjective view.
