[VPB] Please refer to section 5.3 (
https://datatracker.ietf.org/doc/html/draft-bestbar-teas-ns-packet-08#section-5.3
<https://urldefense.com/v3/__https:/datatracker.ietf.org/doc/html/draft-bestbar-teas-ns-packet-08*section-5.3__;Iw!!NEt6yMaO-gk!RKgzM9K5I6Crs9-9OkxWcIvs0atMYM1O1zZWrRa009HkrnmqRqcVdrJg4EU6Aib-$>).
It does note that the usual techniques for steering service traffic onto
paths are applicable -- the example that you cite is certainly allowed. We
can add a reference to draft-ietf-teas-te-service-mapping-yang in this
section and make it explicit.

[VPB] The last two comments above are for the NRP policy data model draft
(Thanks for bringing it up!). We agree that the NRP policy data model draft
needs to be updated to be in sync with the current terminology used in
draft-bestbar-teas-ns-packet. This should get done in the next few days.
But please note that the NRP policy data model draft is not the one that is
currently being polled for adoption.
