Yes, I was aware of this problem, but I was hesitant to solve it since 
it'd require (AFAICT) an extra pass through the style sheet.  I've now 
fixed the problem with a two-pass approach to parsing the style sheet, but 
the processing time has increased by about 75%.  I'm wondering if the 
extra accuracy is worth that much time.

I can eliminate one of the above false warnings without increasing the 
processing time from what it was, but for true accuracy I need two passes 
through the style sheet.

In an ideal world, I'd be a more experienced programmer :)  Extending the 
lint to scan HTML documents has always been in the back of my head, but I 
think it'll stay there awhile longer since the current CSSCheck is 
somewhat slow.  (But maybe this way style sheet authors will be encouraged 
to use external style sheets instead of embedded or inlined style.)

Thanks, I just hope it's fast enough to be useful to the authoring 
community.
