[CSS21] WD 8.4, 10.4: negative percentages

The issue I posted at


concerning the handling of negative percentages of non-positive numbers
still applies to the working draft.

(Summary: "negative values" of padding widths and min-width and max-width
aren't allowed, but the specification isn't clear as to the correct
behaviour if the reference length for the percentage is either 0 or

The above-referenced post currently has one reply, with some opinions on what
some of the behaviour should be.

Not in the above post: the problem exists to some extent with min-height
and max-height, though not as much, because (I believe) the reference
length can't be negative (but can be zero), and (in the case of
min-height) because its default value is zero and it doesn't inherit.
