[spring] draft-ietf-spring-segment-routing-policy

[<[e-mail]>]

Hi authors,

Speaking as individual contributor.

This document seems to define multiple types of segments (1 to 11).
May be this document would be the right place to define them normatively and creates the IANA registry for them. And this seems like a work for spring.
Otherwise, there is a risk that other documents redefine them, possibly in a non-consistent manner. (1) E.g.  the BGP draft is not using the same type numbers/name, which may bring confusion. I would expect YANG models to also need these types.
BTW is there any chance to align the types in the BGP document or is this too late? (alternatively may be changing the types in the sr-policy document)

Thanks,
Regards,
Bruno
