COMMENT:
----------------------------------------------------------------------

In Section 1:

   This document specifies an extension to PCEP to manage of binding
   label/SID for both SR and non-SR paths.

I can't parse this sentence.

The SHOULD in Section 8 seems strange; it offers the implementer a choice of
not allocating the binding label/SID when the PCC has met the stated
conditions.  Why the choice?  If the SHOULD is meant to cover the "unable to
allocate" case, I would argue that the SHOULD is not necessary because there's
no interoperability choice being exercised, and would instead suggest:

   *  To request that the PCE allocate the binding label/SID, a PCC MUST
      set P=1, D=1, and include an empty TE-PATH-BINDING TLV in PCRpt
      message.  The PCE will attempt to allocate it and respond to the PCC with
      PCUpd message including the allocated binding label/SID in the TE-
      PATH-BINDING TLV and P=1, D=1 in the LSP object.  If the PCE is
      unable to allocate, it MUST send a PCErr message with Error-Type =
      TBD2 ("Binding label/SID failure") and Error-Value = TBD5 ("Unable
      to allocate a new binding label/SID").

Thank you for including Section 9.
