What's there should be fine. You might want to explicitly call out the
fact that it IS a matter of (local) policy. Especially since the 
POLICY_DATA gets mentioned, and that object is opaque to the RSVP module
on the LSR. Where the TSPEC, setup and hold priorities could actually be
used by the LSR, the POLICY_DATA can really only be processed by a
policy entity.

Thanks,
