    <d:testDescription xmlns="http://www.w3.org/1999/xhtml" href="http://www.w3.org/TR/SVG11/masking.html#Masking">
      <p>
        Test to see if the masking features using the mask element and mask
        property are available.
      </p>
      <p>
        A red rectangle is displayed in the background to help view the result
        of transparency and masking.
      </p>
      <p>
        From top to bottom, the tests are as follows.
      </p>
      <p>
        In the top test, a linear gradient is used inside the mask to change the opacity
        of the rectangle from 1.0 (at the top) to 0.5 (at the bottom).
      </p>
      <p>
        In the second test, a simple 50% opaque rectangle is used as a mask.
      </p>
      <p>
        In the third test, no mask is used, but a rectangle is shown with 50% opacity.
        The second and third test should look the same.
      </p>
      <p>
        Lastly, a string of text has a mask applied to it. The mask only covers a partial
        area of the text, so the text should only be half visible. Also the mask consists
        of 4 rectangles with various levels of opacity.
      </p>

    <d:operatorScript xmlns="http://www.w3.org/1999/xhtml">

        Run the test. No interaction required.

    <d:passCriteria xmlns="http://www.w3.org/1999/xhtml">
      <p>
        The rendered picture should match the reference image, except
        variations are possible in the labelling text (per CSS2 rules).
