Of these, "shadow" seems to be the least problematic property name.  
The other two imply that you could include the shadow's values in a  
plain "background" or "border" and expect it to work. I'm not sure  
that's possible, wouldn't the parser hiccup when seeing another color  
value, or a pair of unit values? Is there some way to delimit it that  
I'm not aware of, that could make it non-ambiguous? Or would you just  
not have them as part of plain border/background?
