 The proof(s) in the `proof` or  `proofs` parameter MUST incorporate the Credential Issuer Identifier (audience), and optionally a `c_nonce` value generated by the Credential Issuer to allow the Credential Issuer to detect replay. The way that data is incorporated depends on the key proof type. In a JWT, for example, the `c_nonce` value is conveyed in the `nonce` claim, whereas the audience is conveyed in the `aud` claim. In a Linked Data proof, for example, the `c_nonce` is included as the `challenge` element in the key proof object and the Credential Issuer (the intended audience) is included as the `domain` element.

+The `c_nonce` value can be retrieved from the Nonce Endpoint as defined in (#nonce-endpoint).
 
 Additional Credential Request parameters MAY be defined and used.
 The Credential Issuer MUST ignore any unrecognized parameters.
