Styling differently when a replaced element (or a CSS background image) 
is ‘successful’ or not does not only apply to these cases, but also to 
XHTML 1.0 or reasonably common CSS usage (e.g. on my weblog I have a 
green transparent image, which I would like to provide a fallback colour 
other than white for while it’s not loaded yet or when it fails).

This was discussed on www-style not too long ago, however I do not know 
whether the CSS WG did anything with it. I believe it was this thread:

I strongly agree. A limitation in a specific styling language does not 
justify limiting XHTML in its abilities.

*Especially* not in the case of XHTML 2.0, which for the time being 
probably won’t see browser implementations yet, at least until it 
reaches CR. And by that time I think that CSS implementations have 
reached a higher level of CSS support, and the CSS3 specification will 
also have matured more (possibly by cooperation with the HTML WG). 
Talking about not being able to express certain things in CSS for XHTML 
2.0 is mere speculation, unless you can see the future :).

(which, would be a useful ability ;p)
