    <d:testDescription xmlns="http://www.w3.org/1999/xhtml" href="http://www.w3.org/TR/SVG11/filters.html#feOffsetElement">
      <p>
        The target crosshairs should align with
        lower left bounds of the associated circle.
        The color of each crosshair should match
        the associated circle.
      </p>
      <p>
        Verify the basic capability to handle the feOffset, feMerge and
        feFlood filter nodes.  Four copies of a filled circle should appear at
        various offsets and colors.  For each circle a reference crosshair is
        drawn at the lower left of the circle to indicate the expected color,
        opacity and position for the filtered element.  The targets are drawn
        with the standard svg path element.
      </p>
      <p>
        In addition to feFlood, feMerge, and feOffset, this test uses
        'feComposite' to recolor the SourceGraphic with the feFlood color.
        The source graphic uses 'circle'. The target cross hairs are drawn
        with 'path' and use 'fill' and 'fill-opacity'.
      </p>

        The rendered image should match the reference image. Additionally, the
        target crosshairs should match the color, lower left corner, and
        opacity of each copy of the filtered circle.
