I guess I have the same question. Which PCEP document(s) will specify the missing 6 objective functions, listed above, as required in Section 5.1.17 of the PCECP Generic Requirements (RFC 4657)? I don't think these should be specified in 'other' (unnamed) documents, they should appear in the main PCEP specification document http://www.ietf.org/internet-drafts/draft-ietf-pce-pcep-07.txt, or perhaps in draft-leroux-pce-of-00.txt.
