This document has been reviewed as part of the transport area review team's
ongoing effort to review key IETF documents. These comments were written
primarily for the transport area directors, but are copied to the document's
authors and WG to allow them to address any issues raised and also to the IETF
discussion list for information.

When done at the time of IETF Last Call, the authors should consider this
review as part of the last-call comments they receive. Please always CC

This is a straightforward document that extends PCEP (Path Computation
Element Protocol) to include color elements for TE or SR routing.  As a
minor extension to PCEP, it does not raise any significant transport-
related concerns.

I noticed one nit, which is a judgement call.  The authors should review
whether draft-ietf-pce-segment-routing-policy-cp ought to be a Normative
Reference (it's currently informative).  This is a judgement call, as
that referenced draft specifies functionality that excludes use of the
functionality in this draft, hence it is definitely relevant to an
implementer of this draft because the referenced draft limits the scope
of usability.

For clarity, this is a request for review, not a request for change.
Both outcomes (reference remains Informative, reference changed to
Normative) are acceptable to this reviewer.
