Currently we define a specific place in the cascading order for the style  
rules that currently does not exist. Just before author important  
basically.

I suppose we could put background:black accompanied by color:white in the  
normal cascading order for user agent style sheets so people could  
override it easily (and would not make us remove existing backgrounds).

UA does not have an important level. But yes, we could do that. But we  
should include a rule for the color property too.
