RFC 8426 does not look like the correct reference. It does not have a term
called SR-TE.

Also, the quoted text above from RFC8660 is about the forwarding behavior
for Global SIDs. Moreover from the VPN point of view, do we need to
distinguish between the use of a single global SID v/s a stack? Not sure.

I thought maybe we use the term SR-policy but that is applicable for both
SR-MPLS and SRv6. Thus not sure about it.

Same here! :(
Could the IEEE liaison help, or is it a lost cause!

Some like to put a table of all references used in the YANG model in the
core text to make this exercise easier :)

Thanks!
