The content property is restrictive.  Going back to the email I sent in 
about using a pseudo-element to represent mulitple backgrounds (to 
simplify the background property) 
[http://lists.w3.org/Archives/Public/www-style/2006Jan/0022.html], if it 
were then possible to attach a z-index value to the background 
pseudo-element, it would be possible to have mutliple foreground images 
as well as multiple background images.  Content, on the other hand, is 
useful for image replacement, but not for when you want an image to 
overlay text (which does happen).
