<?xml version="1.0"?>
<vxml version="2.0" xmlns="http://www.w3.org/2001/vxml">
 <script>
 <![CDATA[
   function alwaysTrue() {
   // no need to escape the following less than sign
   return 1 < 2;
   }
 ]]>
 </script>
 <block>
  <prompt>
   Hello
  </prompt>
  <prompt cond="alwaysTrue">
   I am always here
  </prompt>
 </block>
</vxml>
</code>

NOTE:

It is wise to put CDATA escapes around your scripts so you don't have to escape XML reserved characters (eg. <, >, &, etc).
