I think this is going to the right direction, it just need some adjustments.

I'll try to create the draft for my proposal of JSON schemas ASAP

I created JSON schemas that I believe (sorry, I didn't test) can validate the data format as it is in this PR:

LGTM! I think this is a good initial set of structs for the attestation parameters negotiation.
