I support WG adoption of the draft, with the following questions. Hope authors can help to explain:

Section 1 Introduction states that the underlay between the Ingress and Egress only needs to support plain IPv6
Forwarding. Those plain IPv6 routers don't need to understand the SR policies encoded in the payload, correct?
Why need Ingress PE to encapsulate the policy sent by egress PE if all the nodes between them are plain IPv6 routers?

Which PE is to enforce the SR policy?
If the policies are for the egress to enforce, why can't the egress PE simply enforce the policy instead of asking ingress node to encapsulate the policy in the packet header? Which has the drawback of extra header bits in packets.
