Registry Context

Technical Summary
RFC 7591 defines invalid_client_metadata as the OAuth Dynamic Client Registration error code used when a client metadata value is invalid and the server rejects the registration request.
When Used
When a registration request contains invalid client metadata and the authorization server chooses to reject the request rather than substitute defaults.
Normative Requirements

RFC 7591 - Section 3.2.2
include an error member containing a single ASCII error code string.
Condition: when constructing a client registration error response

Validation Guidance
Ensure the emitted error code value is exactly `invalid_client_metadata` when this condition applies.
When rejecting a registration request for invalid metadata, verify the response is HTTP 400 with `Content-Type: application/json`.
If the server substitutes a valid metadata value instead of rejecting the request, do not emit this error code.
