Negative percentages for ACSS pause properties



-----BEGIN PGP SIGNED MESSAGE-----

The current ACSS Working Draft [1] does not forbid negative percentages 
for pause-before, pause-after, and pause.  However, these properties take 
either a percentage or a time, and time values cannot be negative.  It 
seems as if the intention is for non-negative percentages for the pause 
properties, though I could imagine negative percentages being used to 
overlap two portions of a document.  (Then again, user agents could not 
properly handle an overlap and still render a document while loading it... 
 I guess this would make negative percentages a Bad Thing.)

So are negative percentage values permitted for pause-before, pause-after, 
and pause?
