In core -23, the last paragraph of section 3.1<http://tools.ietf.org/html/draft-ietf-oauth-v2-23#section-3.1> now says:

                The authorization server MUST ignore unrecognized request parameters.

In -22, this said:

                The authorization server SHOULD ignore unrecognized request parameters.

In a security protocol, it seems unreasonable to require that information be ignored.  As I see it, it SHOULD be legal to return an error if unrecognized information is received.

Why the change?  And can we please have it changed back to SHOULD in -24?

                                                                -- Mike
