It seems to me these checks can be done on three levels:

1 at the css parser level, perfectly possible but computed values for url(#foo) will not
show and that is not what I see in Opera and FF.

2 at the css style selector level, checking the stylesheet baseURL with the doc URL seems
not reliable though when doing run-webkit-tests, I suspect the static cache in
StyledElement.cpp.

3 at rendering time, this has the drawback of slowing down painting.

Since 2 seems the most reasonable (computed values ok and no painting speed loss) I went for
that in my WIP patch. I think right now checking for data: is enough as xml-stylesheet referncing
an external stylesheet seems to wok in all implementations (see for instance LayoutTests/svg/batik/paints/gradientLimit.svg).

I have a testcase handy, just wanted to show the patch and maybe get some feedback on whether this is the right approach.
Cheers,

Rob.
