Note that the syntax for images is significantly different from the syntax for urls. So I suspect you mean <image> rather than <url> above. However it still leaves my original statement unanswered: "Like I said, I think creating an OM that covers all the cases here would create something very complex. I'd love to see a useful proposal for <http://dev.w3.org/csswg/css3-images/>" / Jonas
