[spring] Question for the working group

[Joel Halpern <[e-mail]>]

In regard to Segment Routing Policy as defined by RFC 9256 and the MPLS 
Network Action (MNA) work that is being standardized by the MPLS working 
group, please express an opinion as to whether:

1) An MNA Substack may never be considered a segment in the sense of RFC 
9256 section 4;

2) Some MNA substacks may be considered segments in the sense of RFC 
9256 Section 4 (possibly with a new segment type, possibly with an 
existing segment type)

3) MNA substacks are segments in the sense of RFC 9256 section 4 
(possibly with a new segment type, possibly with an existing segment type)

Yours,

Joel (with Alvaro and Bruno)
