 A public key to be used by the Wallet as an input to the key agreement to encrypt Authorization Response (see (#jarm)). It MAY be passed by the Verifier using the `jwks` or the `jwks_uri` claim within the `client_metadata` or `client_metadata_uri` request parameter.
 
+`client-metadata` and `client_metadata_uri` parameters MUST NOT be used when the Wallet knows Client Identifier and corresponding Client metadata prior to the transaction (i.e., Client Identifier scheme is absent or has value `pre-registered`).

 `request_uri_method`: 
 : OPTIONAL. A string determining the HTTP method to be used when the `request_uri` parameter is included in the same request. Two case-sensitive valid values are defined in this specification: `get` and `post`. If `request_uri_method` value is `get`, the Wallet MUST send the request to retrieve the Request Object using the HTTP GET method, i.e., as defined in [@RFC9101]. If `request_uri_method` value is `post`, a supporting Wallet MUST send the request using the HTTP POST method as detailed in (#request_uri_method_post). If the `request_uri_method` parameter is not present, the Wallet MUST process the `request_uri` parameter as defined in [@RFC9101]. Wallets not supporting the `post` method will send a GET request to the request URI (default behavior as defined in [@RFC9101]). `request_uri_method` parameter MUST NOT be present if a `request_uri` parameter is not present.
