I've embedded a <div> in a  <svg> using <foreignObject>. I want to <animate>its CSS attribute opacity, fading it in when the page has loaded. So I specified an XLink locator, referring to the target element to be animated:
<g xmlns:xlink="http://www.w3.org/1999/xlink">
 <animate xlink:href="#animateThis" attributeType="CSS" attributeName="opacity"  from="0"  to="1"  begin="0s" dur="1s" fill="freeze" />
</g> 
<foreignObject>
 <body xmlns="http://www.w3.org/1999/xhtml">
  <div id="animateThis" style="opacity:0">
   The quick brown fox jumps over the lazy dog.
  </div>
 </body>
</foreignObject>
(The svg is embedded in a HTML5 document).
Testing it in chrome, It doesn't work. On native svg elements however, it does. How do I make this work in objects embedded with <foreignObject>?
