title: how to generate a vxml tag through adynamic ecma/javascript expression
body: <p>I am having issues with the following scenario: 
  my vxml has the following snippet: </p>
  
  <pre><code>&lt;block&gt; 
  &lt;script src="myscript.es"/&gt; 
  &lt;audio&gt; &lt;value expr="temp()"/&gt; &lt;/audio&gt; 
  &lt;exit/&gt; 
  &lt;/block&gt; 
  </code></pre>
  
  <p><strong>myscript.es:</strong> </p>
  
  <pre><code>function temp(){ 
  var delay = new String("abc &lt;break time='2000ms'/&gt; pqr"); 
  return delay; 
  } 
  </code></pre>
  
  <p>The evaluated expression is not being treated as a  tag  rather as follows:
  addd &lt;break time='2000ms'/&gt; bbb</p>
  
  <p>Is there a way to generate a  tag dynamically from ecmascript expression?</p>
