@class  Text
     The Text interface represents the textual content (termed
     character data in XML) of an Element or Attr.
     If there is no markup inside an element's content, the text is
     contained in a single object implementing the Text interface that
     is the only child of the element. If there is markup, it is
     parsed into a list of elements and Text nodes that form the
     list of children of the element.
@extends CharacterData
@param  ownerDocument The Document object associated with this node.
