/**
 * Encapsulate an XML parse error or warning.

 * 
* This module, both source code and documentation, is in the * Public Domain, and comes with NO WARRANTY. * See http://www.saxproject.org * for further information. *
* *

This exception may include information for locating the error * in the original XML document, as if it came from a {@link Locator} * object. Note that although the application * will receive a SAXParseException as the argument to the handlers * in the {@link org.xml.sax.ErrorHandler 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 {@link org.xml.sax.SAXException * SAXException}, it inherits the ability to wrap another exception.
