Re: [csswg-drafts] [css-conditional-4] selector() feature query function for selector support

A missing namespace is a parse error everywhere else, I'd rather be consistent on _rejecting_ it, since not doing that introduces a special-case, and other APIs like `querySelector` already throw on that, like (for example, `document.querySelector("a|b")` throws, doesn't return null).
