None, except for the fact that the in-page script would have to find the
right places to stick those data: URIs, which might be impossible. For
example, if I load a cross-site stylesheet, and it wants to have a
dynamically-generated image like so |content: url("javascript:...")|
then I couldn't handle that via script from my page, because I can't
touch the OM of that cross-site sheet.
