Re: [OAUTH-WG] draft-ietf-oauth-rar use of “WWW-Authenticate” Response Header

The thinking was generally that params of WWW-Authenticate Response Header
Field weren't a great fit for rich JSON authorization data (both in syntax
and semantics).  The authorization detail types are really API-specific
things, and as a result, it's expected that the methods by which clients
obtain or generate the authorization details are also API-specific. Not
sure that exactly answers the question but hopefully helps.
