Hi there,

the minutes 
(<http://tools.ietf.org/wg/httpbis/minutes?item=minutes-90-httpbis.html>) say:

Ted:

1) What exactly are your concerns with respect to use in status codes 
other than 4xx?

2) Regarding another status code: this is not new; RFC 7231 already says 
that 415 is applicable to unsupported content encodings 
(<http://greenbytes.de/tech/webdav/rfc7231.html#status.415>):

> 6.5.13 415 Unsupported Media Type
>
> The 415 (Unsupported Media Type) status code indicates that the origin server is refusing to service the request because the payload is in a format not supported by this method on the target resource. The format problem might be due to the request's indicated Content-Type or Content-Encoding, or as a result of inspecting the data directly.

Why do you think that a new status code is needed here?

Best regards, Julian
