    <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 an <html:code>img</html:code> element with the same <html:acronym>GIF</html:acronym> image.
        The <html:code>alt</html:code> attribute of the <html:code>img</html:code> element identifies the image and conveys the same information.
        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> attribute of the <html:code>img</html:code> element.

    <purpose>
      <p>This test case is intended to pass because the image has an appropriate text alternative in the <html:code>img</html:code> element that serves as a fallback for the innermost <html:code>object</html:code> element. However, 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. Only the image itself is tested, not the image map.</p>

        <p>The <html:code>object</html:code> element has an <html:code>img</html:code> element with an <html:code>alt</html:code> attribute as a fallback .
          Since there is no direct text alternative, it is not entirely clear if this code is accessible.
        </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>
