------- Additional Comments from Dave Hyatt <hyatt at apple.com>
This is really close.  I have two remaining concerns.

(1) Hardcoding of

parentStyle->setUnique();

In CSS3 you'll be able to use the content property without it being in
:before/:after, so I think it's better to actually check what you're matching. 
If you're matching some pseudo-element, then you need to make parentStyle
unique, but if you're not, then you need to make style unique instead.

(2) This second concern could be handled by another patch but is easy to add I
think.	Since this patch was last worked on Rob landed some code for us to
respond to dynamic attribute changes by registering which attribute affect
style.	The attr() construct isn't doing this yet though, so dynamically
changing attributes that don't already cause a setChanged() will fail.

Addressing (1) is enough for me to +.  Addressing (2) is extra credit. :)
