If we think that is the way to go, I like Kio’s proposal over in the CBOR list:
<https://mailarchive.ietf.org/arch/msg/cbor/3sZ4YfWLzmVVnNnQbttkovgjTP8>

We probably should arm that with some text that says (in nicer words) that this is an emergency representation and implementations should not invoke it for sane YANG models (with an operable definition of sane).
