Ah, good question. I guess that depends on whether the "definite size"
already incorporates min/max sizing constraints.

Right now, it seems to me that the spec's definition for "definite size"
does *not* incorporate those constraints, -- it just talks about a
single quantity (a <length>, <percentage>, etc.)[1]

So, I think you probably do want to make the correction apply to both
clauses.

Thanks,
