[Pce] Re: [Idr] WG LC for draft-ietf-idr-sr-policy-seglist-id-09.txt (5/10/2026 to 5/31/2026)

Hi, Sue.

I've reviewed the -09 version and believe it's ready for publication.
This extension improves the visibility and manageability when deploying
SR-Policy via BGP.
I don't think there's a technical flaw in this version.

Many Thanks!
Nat
