The problem is the CSS2 does not restirct to image only in the spec. 
Also, a example of .wav file actually is given in the CSS2 which make it 
not only limited to image.

How about a flash file for icon? does that make sense?
How about a small quicktime movie for icon? does that make sense?
How about an MathML file as before or after? does that make sense?

I agree. One big problem is we can find the SIZE of image or .wav file. 
But there are no way to find the size for the .html.
