    <d:testDescription xmlns="http://www.w3.org/1999/xhtml" href="http://www.w3.org/TR/SVG11/filters.html#feDiffuseLightingElement">
      <p>
        Verify the basic operation of the feDiffuseLighting
        element. The test shows three rows of 3 images. Each
        rows tests a different aspect of the filter and shows
        the result of the filtering operation.
      </p>
      <p>
        The first row shows the result of varying the
        surfaceScale attribute. The second row shows the result
        of varying the diffuse constant (kd) attribute. The last
        row shows the result of varying the lighting-color
        property.
      </p>
