It would be helpful if the examples were full svg documents, feel free to  
check them into the public cvs here:


That's where we put tests that are mostly for discussing a particular

I see no reason why the above shouldn't work in Opera, links (including  
the 'target' attribute) are supported.

This gave the same results in all the browsers I tested just now (safari,  
opera, firefox):

   data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg"><a  
target="foo"/><script>var a = document.getElementsByTagName("a")[0]; var  
target = a.target; alert(target.baseVal + ": should say foo");  
target.baseVal = "_bar"; alert(a.target.baseVal + ": should say  

Again, it would be good with a full testcase to help the discussions.
