Sorry, I didn't have anything concrete in mind - it was really just an
attempt to match a capability of the alternative proposed syntax:
@supports ( display: "bc"; ) {
body { ... }
.sidebar { ... }
.main { ... }
}
Suppose that [display:"bc"] is not actually used in the contained rule
sets, but does appear elsewhere in the file. The feature query would
then depend on something not contained in its block. If there's a
practical example demonstrating the utility of that form, it might be
possible to express the same example using the !support-xxx syntax.
Cheers!
