   * Elements represent most of the "markup" and structure of the

   * (element name and attributes), and any contained nodes, including
   * document text (as children).
   * <p/>
   * Elements may have Attributes associated with them; the API for this is
   * defined in Node, but the function is implemented here. In general, XML
   * applications should retrive Attributes as Nodes, since they may contain
   * entity references and hence be a fairly complex sub-tree. HTML users will
   * be dealing with simple string values, and convenience methods are provided
   * to work in terms of Strings.

   * Namespaces. DeferredElementNSImpl, which inherits from ElementNSImpl, does.
