        <p>
          This test verifies that the <a>'azimuth'</a> attribute is interpreted as a clockwise value in degrees.
        </p>
<p>The test should show four arrows, indicating the direction of the incoming distant light.
        As the four circles are lit by a specular lighting filter a faint shaded arc should appear.
        The middle of each such arc should be where the corresponding arrow points.</p>

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

    <d:passCriteria xmlns="http://www.w3.org/1999/xhtml">
      <p>
        The test has passed if the shaded arcs are displayed only on the side indicated by the arrows.
