 * This class and its sublclass(es) implement the set of interfaces
 * used by the GUI to read and write data.
 *
 * The user may choose to create a new node, enter some data,
 * and then cancel the whole operation. For this reason, the
 * node is not actually inserted into the DOM tree until the
 * user has pressed the "Ok" button.
 *
 * Once this node has been saved for the first time (the user
 * pressed the Ok button) it is no longer valid to use this object
 * for saving further data changes. Thus the first save causes
 * an "invalid" flag to be set and any further calls to the object
 * will then throw an InvalidRequestException.
