  /**
   * The <code>DOMText</code> interface inherits from <code>DOMCharacterData</code>
   * and represents the textual content (termed character data in XML) of an
   * <code>DOMElement</code> or <code>DOMAttr</code>. If there is no markup inside
   * an element's content, the text is contained in a single object
   * implementing the <code>DOMText</code> interface that is the only child of
   * the element. If there is markup, it is parsed into the information items
   * (elements, comments, etc.) and <code>DOMText</code> nodes that form the list
   * of children of the element.
   * <p>When a document is first made available via the DOM, there is only one
   * <code>DOMText</code> node for each block of text. Users may create adjacent
   * <code>DOMText</code> nodes that represent the contents of a given element
   * without any intervening markup, but should be aware that there is no way
   * to represent the separations between these nodes in XML or HTML, so they
   * will not (in general) persist between DOM editing sessions. The
   * <code>normalize()</code> method on <code>DOMNode</code> merges any such
   * adjacent <code>DOMText</code> objects into a single node for each block of
   * text.
   * <p>See also the <a href='http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113'>Document Object Model (DOM) Level 2 Core Specification</a>.
