    <h2>Description</h2>
    <p>An element with an aria-live attribute is added to the document by a script 
      during the onload event with the value="polite" and the element has a child 
      DOM element node that contains text content. After the onload event completes 
      the CSS 'visibility' property of the child DOM element node is changed 
      to visibility="hidden".</p>
    
    <script type="text/javascript">

        var node  = document.getElementById('TEST_ID_2');

      }
