Re: [pcp] WGLC: draft-ietf-pcp-third-party-id-option-00 comments due by JAN 7

A copy with my comments inline is now at
http://research.microsoft.com/~dthaler/draft-ietf-pcp-third-party-id-option-00.pdf

Summary:
1) Too many places are still worded to be about "tunnel ID" rather than "third party ID".
   This draft shouldn't assume tunnels, that's just one example case.
2) Need to explicitly state the assumption that the same PCP-IWF serves multiple subscribers.
    (It was implicit currently, but should be explicit.)
3) Need to explicitly state the assumption that the PCP client and PCP server have some
    out-of-band mechanism to agree on what to put in the THIRD_PARTY_ID field.
    (Again it was implicit, but should be explicit.)
4) Section 5.2 on processing a request needs to cover the success case, not just the error case.
    And I believe that behavior changes the basic rules in RFC 6887 and hence this document
    should Update 6887.  I.e. you cannot simply implement this as a layer on top of an
    unmodified 6887-compliant PCP implementation.
5) Section 5.3 on processing a response has a new requirement "SHOULD report an error"
     which is not in RFC 6887 section 11.4 or 12.4.   Is this really a requirement?  I'm ok
    either way, but not sure why this specific error response would be special in terms
    of what should be reported to somewhere.
