      <p>
        Test to see the effect of applying an opacity property to a group.
      </p>
      <p>
        A blue rectangle with a green rectangle on top are contained in a
        group. This opacity of the group and the opacity of the rectangles are
        changed in this test. A red rectangle is provided in the background so
        that opacity changes are obvious visually.
      </p>
      <p>
        From top to bottom, the tests are as follows.
      </p>
      <p>
        In the top test, the opacities of the group and the individual rectangles are
        all set to 1. 
      </p>
      <p>
        In the second test, the group is given an opacity of 0.5. 
      </p>
      <p>
        In the third test, the group maintains a group opacity of 1 whereas each individual
        rectangle is given an opacity of 0.5 in the group. 
      </p>
      <p>
        Lastly, the group and individual rectangles are all given an opacity of 0.5.
      </p>


    </d:testDescription>
    <d:operatorScript xmlns="http://www.w3.org/1999/xhtml">
      <p>
        Run the test. No interaction required.
      </p>
    </d:operatorScript>
    <d:passCriteria xmlns="http://www.w3.org/1999/xhtml">
      <p>
        In the top test, the green rectangle should appear on top of the blue
        rectangle.
      </p>
      <p>
        In the second test, the blue
        rectangle should not show through in the region where the green and blue overlap.
      </p>
      <p>
        In the third test, the blue rectangle
        should show through in the overlap region.
      </p>
      <p>
        Lastly, the
        result should be similar to the previous test only fainter (because the opacity) is
        resulting in less contribution.
      </p>
      <p>
        The rendered picture should match the reference image exactly, except for possible
        variations in the labelling text (per CSS2 rules).
