RE: [css3-multicol] should 'column-count' accept negative values?

We should really make this not only say this cannot be negative. We should explicitly state that value must be 1 or greater.

I agree that negative valued don't make sense. The same can be said
for widows and orphans, but we don't disallow negative values for
those:

Perhaps we should. For other properties, we say (in prose) that
"negative values are not allowed":

  http://www.w3.org/TR/2006/WD-CSS21-20061106/visudet.html#propdef-line-height

Do you propose to address this the same way? That is, by adding prose?
