I would have guessed that an unknown media type is something that a) 
matches the parsing rules for a media type and b) is unknown (undefined) 
in a specific version of CSS.

So my reading was that e.g. "&test" does not meet a) and so is not an 
unknown media type, but part of a malformed statement.

If this is the intention of CSS 2.1 then, yes, it should be made more clear.
