The SAXException interface encapsulates a general SAX error or warning.
This interface 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.
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.
If the parser or application needs to include information about a specific location in an XML document, it should use the SAXParseException subclass.
