  <formalMetadata xml:lang="en">
      <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 an <html:code>img</html:code> element with the <html:acronym>GIF</html:acronym> version of the same image.
        The <html:code>alt</html:code> attribute of the <html:code>img</html:code> element identifies the image and conveys the same information.
        However, the <html:code>alt</html:code> attribute of one of the map's <html:code>area</html:code> elements is empty.
        The  <html:code>object</html:code> element does 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 fail because one of the areas of the image map has no text alternative. The empty text alternative is an issue in itself, but, in addition to this, browser support for the <html:code>object</html:code> element may also determine if this test case is accessible or not. Internet Explorer has weak or no support for the <html:code>object</html:code> element.</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.
              However, since the second <html:code>area</html:code> element in the map <html:code>element</html:code> has an empty <html:code>alt</html:code> attribute, this case does not pass. 
           </p>
           <p>This test case is identical to xhtml1_wcag2_20050630_1.1_l1_sc1_011, except that the second <html:code>area</html:code> has an empty <html:code>alt</html:code> attribute.</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> but displays the fallback image.)</p>
