I think we have accepted that this WG will do standardization for / around the following attestation token formats (aka attestation evidence formats):
EAT (lots of detailed work in IETF to define)
JWT
CWT
(possibly also ASN.1 / X.509)
TCG (fixed years ago by the TCG)
TPM 1.2 signed Quote
TPM 2 signed Audit Session

I think any conveyance protocol we work on MUST carry all of these. I don’t think this is hard. If it were hard I wouldn’t say this.

To adopt the YANG module, I think it should be modified to carry EAT/JWT/CWT and retain its name. It can still have the other TPM-specific stuff in it for use when in TPM mode, but it should have an EAT mode too.
