Arguably, it varies by descriptor, and maybe some descriptors should instead of declaring values illegal, they should declare them as never matching.

For instance, with the current definitions, (width < -1px) is unknown, but maybe having it be false would make more sense. And we might want to go as far as making (width > -1px) be true on any visual medium.
