    <d:testDescription xmlns="http://www.w3.org/1999/xhtml" href="http://www.w3.org/TR/SVG11/filters.html#feDistantLightElevationAttribute">
        <p>
          This test verifies that the <a>'elevation'</a> attribute is interpreted as a
          complementary value to the z-axis in degrees.
        </p>
        <p>
          The test shows four different elevation angles that can be used for feDistantLight source.
          The four different feDistantLight light sources are used in three different filter cases; feDiffuseLight, feSpecularLight
          and feMerge which merges both feDiffuseLight and feSpecularLight to form a single filter. Using four different elevation values
          in three different filter cases gives twelve different filters. All twelve filter cases are applied to a vector graphic and
          then to a raster graphic. The vector graphic results are shown to the left and the raster graphic results are shown to the right.
