I have a few comments / questions about draft-raza-ace-cbor-certificates-04.txt section 6 on native CBOR certs

When you sign CBOR, usually it is wrapped in a bstr. This is important to be able to use typical CBOR encoders/decoders. This doesn’t seem to be the case here, at least I don’t see it in the text near the end of section 3.

Was any consideration given to using the COSE algorithm registry rather than defining a new one?

But of most interest to me is whether the COSE was considered as the signing format for native CBOR certs. If COSE is used, then this looks almost identical to CWT and may be a native CBOR cert is a variant of a CWT? One advantage of this would be reuse of some of the CWT (and EAT) code. Some of the fields in the CBOR cert might overlap with CWT claims. That might be a good thing.
