Publication is requested as a Standards Track RFC.   
This is appropriate because the document defines extensions to a
protocol that is already published on the Standards Track. These
extensions are intended for implementation and deployment.
This is indicated in the header of the document.

> Technical Summary

The Path Computation Element (PCE) has been identified as an
appropriate technology for the determination of the paths of 
point-to-multipoint (P2MP) TE Label Switched Paths (LSPs). 

This document provides extensions required for Path Computation
Element Communication Protocol (PCEP) so as to enable the usage
of a statefulPCE capability in supporting P2MP TE LSPs.

> Working Group Summary

The working group process has been uneventful. The author team
comes from vendors and operators who ship and deploy P2MP
RSVP-TE and so have a very strong interest in these PCE 
extensions.

IANA Early code point allocation was made for the code points
needed by this work.

> Document Quality

This document received only moderate review during its time in
the working group. P2MP function is somewhat fringe, and so 
only a small group of people worked on it. As a result, WG last
call was quiet.

The document shepherd (Adrian Farrel) and the out-going chair
(Jon Hardwick) made a detailed reviews that led to a number of
minor changes.

Implementation status is not known, but it is believed that 
two vendors have roadmap plans.

> Personnel

Adrian Farrel (adrian@olddog.co.uk) is the Document Shepherd

Deborah Brungard (db3546@att.com) is the Responsible
Area Director

The Shepherd did a detailed line-by-line review and the authors
made appropriate updates. This revision is ready for publication.

Good enough. Could have used more, but it will do.

>     If so, describe the review that took place.

No. There are some parts that use RBNF. They are not normative,
but have had careful scrutiny from PCEP experts.

No such concerns.

A poll was carried out on the mailing list and all authors
explicitly confirmed their compliance.

No IPR has been disclosed.

General agreement that the work should be done, but light interest
in the details beyond the author team and reviewers. No dissent.

> (10) Has anyone threatened an appeal or otherwise indicated

No.

Only problem is s/[This I-D]/[This.I-D]/

>      and URI type reviews.

No such requirements.

Yes

No issues.

No Downrefs

No.

Everything looks good.
A substantial set of early allocations were made in April 2018
and this publication request (with the IANA section) requests
IANA to confirm those assignments.

This document makes no requests to modify or remove any of the
early allocations, however, section 10.7 does request the 
creation of a further registry. This is well defined.

None

RBNF reviewed manually.
