    <h2>Description</h2>
    <p>The aria-live attribute is added to an element in the document by a script 
      after the onload event completes with the value="polite" and the element has 
      a child DOM element node that contains text content. After the aria-live 
      attribute is added, the child DOM element node is deleted.</p>
    
    <script type="text/javascript">  

      function deleteChildNodes() {
        var node  = document.getElementById('TEST_ID_1');  
        while (node.firstChild) node.removeChild(node.firstChild);
      }

      function addLiveRegion() {
