Note that Gecko has serious security concerns with allowing subresource 
loads like this in SVG loaded via <img>; we currently disallow them 
altogether due to those concerns.  Such SVG documents can link to things 
internal to themselves and to data: URIs, but not to anything requiring 
network access.

SVG loaded via <object> is a different story, of course.
