Thank you for that feedback.

So I think we need to be a bit more radical/precise:

-YANG-CBOR should explain that SIDs are 63-bit unsigned integers and how the delta encoding in the CBOR map keys works.  I.e., define the concept, but not the number space management.

-sid does the latter.

The document that defines the media types (comi) gets to bind YANG-CBOR, for these media types, to the specific SID concept defined in -sid.

-YANG-CBOR can still refer to -sid as a preferred way to manage the number space.
But you can implement -YANG-CBOR without understanding -sid, so this is not a normative reference.
Any other document using -YANG-CBOR can refer to -sid as well (or, exceptionally, to something specific for that usage).
