Summary: This document provides a well-structured and technically sound specification for SR P2MP Policies. 

Questions: 
The document does not describe inter-domain or multi-controller scenarios.
- Are SR P2MP Policies scoped to a single domain?
- How are overlapping Tree-IDs managed across controllers or root nodes?
- What happens if a controller fails to install all Replication Segments?

NITS : 
Abstract: "Candidate Paths and and how P2MP trees..." -> Duplicate “and”.
Section 1: "instantiate a P2MP tree instance in the SR domain..." ->  Should be “instantiates”
Section 2.3: “An SR P2MP Policy can has one or more CPs…” -> Typo: should be “can have.”
Section 4.4: “Some example of these mechanisms are PCEP, BGP and NetConf.” ->  Should be “examples”
