== ECDAA verification algorithm in TPM Attestation Statement Format ==
I wonder what is ECDAA verification algorithm in TPM Attestation Statement Format.
In draft specification it linked in FIDO ECDAA. but TPM Part1 Architecture specifies EC Schnorr Signature Validation. (i.e ECDAA signature algorithm in TPM is modified Schnorr Sign)

If it follows in FIDO ECDAA, then i wonder how to resolve credentials (R,S,T,W).
Thank you for your advice.
