The core specification (http://openid.net/specs/openid-connect-core-1_0.html) incorrectly specifies that "application/x-www-form-urlencoded" form should be used for encoding query param values in a *URL*. Despite its name, application/x-www-form-urlencoded is only for the body of an HTTP request. The biggest different is in how PLUS and SPACE characters are encoded/decoded. The examples, however, actually encode SPACE correctly in a URL, using %20, rather than as '+' (if form encoding format were really being used).

In the examples that use POST to send params, application/x-www-form-urlencoded makes sense, but the examples show %20 used to encode SPACE, rather than '+'.

The scenario where this is most likely to cause a problem would be if a param value ever needed to contain a '+' character.
