Re: [OAUTH-WG] draft-zhang-jose-json-fine-grained-access

Some thoughts in no particular order, but mostly I'm with Justin:

   1. The exact data properties of the json probably don't belong in this
   RFC, but rather can be used as an example in the RFC rather than
   anything normative, as the structure defined herein is not sufficient in
   many cases. Depending exactly on how (#2) is done, needs to be more
   extensible or potentially completely ignored since any JSON or even string
   could be used to achieve #2.
   2. The mechanism of how to use the json to encrypt and decrypt the
   message feels like the only relevant/interesting detail here and it is the
   main detail left out.

I'd recommend cutting the context related to the structure of the request
(#1) and focus on how it will be used to encrypt/decrypt payloads (#2).
