- * method. The parser will then report all errors and warnings
- * through this interface.</p>

- * provide useful information after a call to fatalError (in other
- * words, a SAX driver class could catch an exception and report a
- * fatalError).</p>
- *
- * <p>The HandlerBase class provides a default implementation of this
- * interface, ignoring warnings and recoverable errors and throwing a
- * SAXParseException for fatal errors. An application may extend
- * that class rather than implementing the complete interface
- * itself.</p>
