Encapsulate an XML parse error or warning.
This exception may include information for locating the error in the original XML document, as if it came from a Locator object. Note that although the application will receive a SAXParseException as the argument to the handlers in the ErrorHandler interface, the application is not actually required to throw the exception; instead, it can simply read the information in it and take a different action.
Since this exception is a subclass of SAXException, it inherits the ability to wrap another exception.
