        Test SVGElementInstance.childNodes.
      </p>
      <p>
        The test has an optional subtest that indicates whether SVGElementInstance.firstChild and
        SVGElementInstance.childNodes.item(0) are strictly equal. The status of this subtest is
        displayed by a circle in the middle of the testframe, it will be yellow if the objects are
        not strictly equal, and green if they are.
      </p>

    <d:operatorScript xmlns="http://www.w3.org/1999/xhtml">
      <p>
        Run the test. No interaction required.

      <p>
        The test is passed if there is a green rect visible,
        and there is a yellow or dark green circle in the middle. 
        If there's any red visible the test has failed.
