"Supported" is not enough.  A text browser (like w3m) may support CSS 
and images, but if it runs in remote shell, it may not render 
background-image and designer may want a background-color to take effect 
instead of background-image in this case.  Turned off images is another 
example.

I consciously choose example that is similar to my unreplied proposal in 
http://lists.w3.org/Archives/Public/www-style/2005Mar/0155.html .  I 
don't insist on the exact syntax or names.
