The `<mf-range>` syntax allows:

```
<mf-range> = <mf-name> [ '<' | '>' ]? '='? <mf-value>
           | <mf-value> [ '<' | '>' ]? '='? <mf-name>
```

That is, both `500px > width` and `width > 500px` is valid.

This is nice, but given `<mf-value>` can also be an `<ident>` it causes ambiguity, and complexity / slowness while parsing.

Given you can easily use negations, I think it's not terribly useful, but if people feel very strongly about it the spec should define how to resolve the syntax ambiguity.
