title: SVG xml:base attribute not working in IE9
body: <p>I'm trying to create an SVG document that includes image tags referencing png files. This works if I include the absolute path of the png in every image tag but if I try putting an xml:base attribute in it doesn't seem to work in IE9. However it does seem to work Firefox and Chrome. Is there a bug in IE or is there something wrong with my syntax?</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="yes" ?&gt;
  &lt;svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xml:base="file:///C:/SVG/Devices/valves/"&gt;
    &lt;image width="40" height="56" x="10" y="10" xlink:href="motorised_valve[purple].gif"/&gt;
  &lt;/svg&gt;
  </code></pre>
  
  <p>For complicated reasons I don't want to go into here, I can't put the SVG document into the same folder as the images.</p>
  
  <p>Thanks for any help
  Mog</p>
