Unsupported format - HTTP error code

Hi there!

In section 2.21.0.1.4 - Wire Format Representations it is stated in the FHIR spec, that a server should return an HTTP 415 error, if a client requests a Conformance statement in an unsupported format. Unfortunately, I cannot find any reference for that in the description of the REST API (section 2.42.0.15 conformance). Would anyone be so kind as to clarify this situation a bit, please?

Also, should a 415 be returned for resources other than a Conformance statement?

Best regards,
