That doesn't cover nearly all the ways you can use URLs as defined in
http://dev.w3.org/csswg/css3-images/ which support multiple levels of
fallback images, with snapping and resolution as well as gradients and
fallback colors. And with used in a property like backgroundImage, you
can have several combined instances of those. Consider:

style="background-image: image(sun.svg, 'sun.png' snap 150dpi),
image(wavy.svg, 'wavy.png' 150dpi, 'wavy.gif', radial-gradient(...))"
