+
+        The UserInfo Claims MUST be returned as the members of a JSON object
+         unless a signed or encrypted response was requested during Client
+         Registration. The Claims defined in Section 5.1 can be returned, as can
+         additional Claims not specified there.
+
+        For privacy reasons, OpenID Providers MAY elect to not return values for
+        some requested Claims.
+
+        If a Claim is not returned, that Claim Name SHOULD be omitted from the
+        JSON object representing the Claims; it SHOULD NOT be present with a
+        null or empty string value.
+
+        The sub (subject) Claim MUST always be returned in the UserInfo
+        Response.
+
+        Upon receipt of the UserInfo Request, the UserInfo Endpoint MUST return
+        the JSON Serialization of the UserInfo Response as in Section 13.3 in
+        the HTTP response body unless a different format was specified during
+        Registration [OpenID.Registration].
+
+        If the UserInfo Response is signed and/or encrypted, then the Claims are
+        returned in a JWT and the content-type MUST be application/jwt. The
+        response MAY be encrypted without also being signed. If both signing and
+        encryption are requested, the response MUST be signed then encrypted,
+        with the result being a Nested JWT, as defined in [JWT].
+
+        If signed, the UserInfo Response SHOULD contain the Claims iss (issuer)
+        and aud (audience) as members. The iss value SHOULD be the OP's Issuer
+        Identifier URL. The aud value SHOULD be or include the RP's Client ID
+        value.
