One further thought based on our discussion of element(). We discussed 
that we want to be able to use masks without requiring the <mask> 
wrapper, e.g.

   <rect id="rect" ... />
   <path mask="url(#rect)" ... />

I wonder if it's useful to say that, in order to refer to SVG fragments 
in this way you must use the element() syntax. i.e. the url() syntax is 
only for <mask>s and other SVG elements which we treat specially, rather 
than just rendering them to a buffer (like paint servers).

So for the above you'd use:

   <rect id="rect" ... />
   <path mask="element(#rect)" ... />

"mask: url(#rect)" would be invalid. Then we reserve url() + # for 
referring to <mask> elements or paint servers. I'm not sure if that's a 
helpful restriction or just confusing.

Of course, url(abc.png) is still fine.
