I assume "The format of the content is "application/rs-metadata", and the body is an XML document, the format of which is defined in RFC7865." as per RFC7866.

Furthermore you can file an enhancement bug report to request the addition of the interpretation of this MIME type. Please include a sample capture file to the bug for test and verification purposes.
