Hi Cheng, I've reviewed the latest version of this draft, and think it provides a useful mechanism for SRv6 as RFC 9545 does for SR-MPLS. Thus I support moving it forward.
I have one small comment which could be considered either before or as part of the WG LC. In section 3, it says an SRv6 path segment can identify "an SRv6 path or a set of SRv6 path". It is suggested to clarify the scope of the "SRv6 path" here. To my understanding it actually refers to one or multiple SRv6 segment lists of a particular SRv6 policy candidate path. As mentioned in the introduction section, the same segment list may be used by different SRv6 policy candidate paths, and the path segment is used to distinguish the segment list of different candidate paths for performance measurement.
