Test Case

http://tools.ietf.org/html/rfc2616#section-3.7 says that media-type should be
type "/" subtype *( ";" parameter ) , where type and subtype both are tokens.
http://tools.ietf.org/html/rfc2616#page-17 says that tokens should not contain
CTL's or separators, hence according to section 4.B.d of
http://dev.w3.org/2006/webapi/FileAPI/#slide-method-algo, it should throw a
SyntaxError, but it does not.

I feel the spec doesn't match implementation.
