we are validating the dynamic client registration but we are seeing some of the test cases are failed. Need some clarifications, we have followed the below steps
1. We passed the test case IIA2c where it accepts the POST request for the registration endpoint and we are getting the valid response
2. But for the other test case IIA3a2, since the request doesn't have an "x5c" header the response should be an error response but when we send the error response test script is expecting other parameters also in the response like "client_id", "software_statement" with all the 9 parameters. Is this the expected behaviour? if Yes, what should be parameter value for this.
3. Can you guide us on any kind of document for this test cases workflow or is there any sequence si defined to execute these test cases.
