In WebCore we handle this through lazy updating of the style  
attribute. See WebCore/dom/StyledElement.cpp and related code in  
element.cpp. It might be useful to make this concept a bit more  
general in the future, since HTML5 classList may make it desirable to  
do similar lazy updating for the class attribute.
