All, A revised CBOR RFC has been published and it includes an top-level section on what it now calls "deterministic encoding" [1] which should help clarify what BPv7 and BPSec are already specifying as "canonical encoding". Since BPv7 and BPSec don't use CBOR maps, the rules of deterministic encoding are already what was used or assumed. Since the old RFC 7049 is now obsoleted, it would probably be good to point the draft BP specs at RFC 8949. I suspect the I-D nit checker would now complain about the old reference.
