 * An exception that can be thrown by a StatementHandler when it
 * encounters an application specific error that should cause the
 * parser to stop. If an exception is associated with the error then
 * this exception can be stored in a StatementHandlerException and
 * can later be retrieved from it when the StatementHandlerException
 * is catched, e.g.:
 * <pre>
 * try {
 *   parser.parse(myInputStream, myBaseURI);
 * }
 * catch (StatementHandlerException e) {
 *   Exception myException = e.getSource();
