vxml element

Represents the root document element of a VoiceXML document.

xml:lang = "string"
/>

Attributes

application	The URI of the application's root document.
base	DEPRECATED. Use xml:base instead.
version	The version of VoiceXML to which the VoiceXML document conforms. Developers authoring applications to run on the Tellme platform should set this value to 2.1.

Remarks

The vxml element can contain one or more dialogs. It can also contain data, grammars, links, scripts, and variables declared at document scope.

Examples

When the Tellme VoiceXML interpreter executes the following VoiceXML document it converts the string "Hello World!" to speech, plays that string to the user, and then transitions to the main Tellme service menu.

<?xml version="1.0"?>
<vxml version="2.1"
 xmlns="http://www.w3.org/2001/vxml">
<form>
   <block>
      Hello World!
      <exit />
   </block>  
</form> 
</vxml>
