IETF Last Call Review of draft-ietf-ccamp-rfc9093-bis-15
review-ietf-ccamp-rfc9093-bis-15-opsdir-lc-chen-2025-06-26-00

I have reviewed this document as part of the Operational Directorate's ongoing
effort to review all IETF documents being processed by the IESG. These comments
were written with the intent of improving the operational aspects of IETF
drafts. Comments that are not addressed during the last call may be included in
AD reviews during the IESG review. Document editors and WG chairs should treat
these comments like any other last call comments.

This document obsoletes [RFC9093] by replacing it in its entirety. It provides
a new revision of the YANG module contained in that RFC, and retains the data
types previously defined, but also adds new type（ietf-layer0-types ）definitions
to the YANG module. The document is clear and well-written. The motivation is
described well. The document is almost ready for publication.

## Minor
1.For Normative References:
Please pay more attention to ​​draft-ietf-teas-rfc8776-update-17​​, which has
not yet entered the IESG process. 2. The following text points to non-existent
sections. [I-D.ietf-ccamp-optical-impairment-topology-yang] does not contain
Section 2.5.2. Was "Section 2.6.2 of
[I-D.ietf-ccamp-optical-impairment-topology-yang] perhaps intended as shown
below Current: Section 2.5.2 of
[I-D.ietf-ccamp-optical-impairment-topology-yang] Perhaps: Section 2.6.2 of
[I-D.ietf-ccamp-optical-impairment-topology-yang]
