I was asked to review revision 11 of this draft as part of the IntArea directorate.
Since then revision 13 has been posted and I've revised this review to that version.
This review is for the Int AD IESG review and may be considered by authors as
last call review comments.

General Observations:
The specification is compact and the wire encoding is straightforward.
The encoding and the separation between BGP validation and SR Policy 
Module (SRPM) semantic processing are consistent with RFC 9830.

After reviewing the draft and its normative references I'm left with one
ISSUE around validity checking.

This draft defines the NRP ID Sub TLV and its encoding, but
does not specify, nor fully abdicate, the validity checking of the NRP ID to
draft-ietf-spring-sr-policy-nrp.

draft-ietf-spring-sr-policy-nrp-02 does not yet define
deterministic behavior when a syntactically valid NRP association cannot be
used by the receiving head end.

Further more this draft contains select normative language about how NRP IDs are
associated with candidate paths, but that text says essentially nothing normative.

This draft states in Operational Considerations:
    Although the updates to SR Policy architecture in
   [I-D.ietf-spring-sr-policy-nrp] allow different candidate paths in
   one SR Policy to be associated with different NRPs, in normal network
   scenarios it is considered that no matter which candidate path is
   active, the association between an SR Policy and NRP is consistent.
   In such case all candidate paths of one SR Policy SHOULD be
   associated with the same NRP.  The cases where different candidate
   paths of an SR Policy are associated with different NRPs is valid but
   NOT RECOMMENDED.

This does not tell an implementor of this specification anything other than "anything other NRP ID 0 is valid".

ISSUE 1: I suggest this text say something deterministic or is removed completely and replaced
with text stating "NRP ID validation is out of scope and defined in draft-ietf-spring-sr-policy-nrp"

ISSUE  2 (not an issue for this draft): In addition draft-ietf-spring-sr-policy-nrp
should be updated at the earliest to specify normative validity checking 
of NRP IDs and the requirements around their permitted values in SR Policy
candidate paths, and their lack of existence when NRP ID 0 may be received
but the TLV is ignored.
