[Openid-specs-fapi] Issue #181: Userinfo response should be a jwt. OP's should support UserInfo JWT response (openid/fapi)

New issue 181: Userinfo response should be a jwt. OP's should support UserInfo JWT response
https://bitbucket.org/openid/fapi/issues/181/userinfo-response-should-be-a-jwt-ops

Ralph Bragg:

OpenID Connect core details how the userinfo endpoint responses can be provided as either a JSON payload or a JWT depending on the accept headers on the GET request.

If a FAPI profile is being used to provide Identity Information then OPs should certainly be providing the UserInfo endpoint as a signed JWT.

Suggest adding this to the next implementors draft.
