      <description>A document with  an <html:code>object</html:code> element in an image map. The <html:code>object</html:code> element embeds an image in <html:acronym>PNG</html:acronym> format, and 
        contains another <html:code>object</html:code> element that embeds the <html:acronym>GIF</html:acronym> version of the same image. This second <html:code>object</html:code> elment contains only the image map.
        The  <html:code>object</html:code> elements do not have a  <html:code>title</html:code> attribute or any other text alternative except the <html:code>alt</html:code> attributes of the map's <html:code>area</html:code> elements.

      <purpose>
         <p>It is not entirely clear if this test case fails. The innermost <html:code>object</html:code> element does not contain an <html:code>img</html:code> element with an <html:code>alt</html:code> attribute, but it contains the image map, and each area in the image map has an <html:code>alt</html:code> attribute that conveys the same information as the area, and the image itself is identified in the text above it. 
          In addition, browser support for the <html:code>object</html:code> element may determine if this test case is accessible or not. Internet Explorer (version 6 or earlier) has weak or no support for the <html:code>object</html:code> element.</p>

          <p>(In Mozilla 1.7.3 and Firefox 1.0, the map does not work if the <html:code>map</html:code> element has only an <html:code>id</html:code> and no <html:code>name</html:code> attribute.)</p>
          <p>(Internet Explorer does not support <html:code>object</html:code> so the test does not work in this browser.)</p>
