Child tag

VoiceXML, which is an XML format, is structured as a tree of elements, or text enclosed in markup tags. Nesting tags creates a hierarchy of elements that is traversed by the Plum VoiceXML platform to direct your callflow. A child tag is a tag that is enclosed by another tag. VoiceXML has limitations on the valid types of child tags for each VoiceXML tag.

For example, in the following code, <block/> is a child tag of <form/>, and <prompt/> is a child tag of <block/>.

<form>
  <block>
    <prompt>This is a fragment of VoiceXML.</prompt>
  </block>
</form>
