+ * <p>This class can contain basic error or warning information from
+ * either the XML parser or the application: a parser writer or
+ * application writer can subclass it to provide additional
+ * functionality.  SAX handlers may throw this exception or
+ * any exception subclassed from it.</p>
+ *
+ * <p>If the application needs to pass through other types of
+ * exceptions, it must wrap those exceptions in a SAXException
+ * or an exception derived from a SAXException.</p>
+ *
+ * <p>If the parser or application needs to include information about a
+ * specific location in an XML document, it should use the
+ * {@link org.xml.sax.SAXParseException SAXParseException} subclass.</p>
