   * interface.</p>

   * <p>If an application does <em>not</em> register its own custom
   * <code>ErrorListener</code>, the default <code>ErrorListener</code>
   * is used which reports all warnings and errors to <code>System.err</code>
   * and does not throw any <code>Exception</code>s.
   * Applications are <em>strongly</em> encouraged to register and use
   * <code>ErrorListener</code>s that insure proper behavior for warnings and
   * errors.</p>
   *
   * <p>For transformation errors, a <code>Transformer</code> must use this
   * interface instead of throwing an <code>Exception</code>: it is up to the
   * application to decide whether to throw an <code>Exception</code> for
   * different types of errors and warnings.  Note however that the
   * <code>Transformer</code> is not required to continue with the transformation
   * after a call to {@link #fatalError(TransformerException exception)}.</p>
   *
   * <p><code>Transformer</code>s may use this mechanism to report XML parsing
   * errors as well as transformation errors.</p>
