[OpenID] Content-Type for Key-Value Form response from OP

Since openid has its own discovery protocol (leveraging iana registered mime types) we can stick with x- labels. We know from discovey what the application context is (openid auth protocol, yadis protocol, extension protocols, hxri url resolution). We don't need iana to give to context with a registered mime type for the wire protocol . One thus avoids being beholden to iana/ietf processes, and its security area directorate. The independence is worth it, at this stage of development of the movement: as ietf layer8 politics would eat openid alive. Like ssl, once mature and unavoidable, then let ietf bring its engineering process to bear, for the long term viability of the standard.

Hi Andrew,

Sorry I didn't see your messages until now.

I believe the convention for unregistered MIME types is to prefix the
subtype part with "x-", giving something like text/x-kvf.

However, since the spec mandates UTF-8 for this message format, it may
be more appropriate to use an "application/" type; text types generally
support a "charset" attribute allowing the content to be in an arbitrary
character encoding, which is not appropriate here.
