   * Wraps {@link XMLErrorHandler} and make it look like a SAX {@link ErrorHandler}.
   *
   * <p>
   * The derived class should override the {@link #getErrorHandler()} method
   * so that it will return the correct {@link XMLErrorHandler} instance.
   * This method will be called whenever an error/warning is found.
   *
   * <p>
   * Experience shows that it is better to store the actual
   * {@link XMLErrorHandler} in one place and looks up that variable,
   * rather than copying it into every component that needs an error handler
   * and update all of them whenever it is changed, IMO.
