Good point. Would this help?

Section 1.1 (last paragraph), ADD:
  For instance, a policy rules document could be used to express the agreed policy. Formal policy documents, such as [RFC4745], can be applied in an automated fashion by a LIS.

That text sounds OK. Actually, since this is just a (poor) paraphrase of RFC 5687, maybe we could instead lift that text:
 
      The LIS MUST be able to use the identifier [...] for location determination.

Would this plagiarism work for you?

It was always the intent to use GRUU :)

Section 3.5, OLD:
   ... For example, a SIP address of record URI can
   correspond to a service subscription rather than a single Device.
NEW:
   ... For example, a SIP address of record URI can
   correspond to a service subscription rather than a single Device;
   a Globally Routable User Agent URI (GRUU) [RFC5627] might be more
   appropriate.

Cheers,
Martin
