This would be against my previous wish to support SVG stacks for URLs, but it might be a consensus that we all can live with.

Here a short example. On a CSS Image value, we would always interpret:

	url(file#frag)

as a reference of a SVG resource (like SVG Paint Server, Masker, Clipper, Filter or Marker) and

	url(file)

as an image. Media fragments would require the 'image()' function. Note that I brought this issue up for the next FXTF call.
