* @brief ACEXML_ErrorHandler
*
* If a SAX application needs to implement customized error handling,
* it must implement this interface and then register an instance with
* the XML reader using the setErrorHandler method. The parser will
* then report all errors and warnings through this interface.
*
* @b WARNING: If an application does not register an ErrorHandler,
* XML parsing errors will go unreported and bizarre behaviour may
* result.
*
* For XML processing errors, a SAX driver must use this interface
* instead of throwing an exception: it is up to the application to
* decide whether to throw an exception for different types of errors
* and warnings. Note, however, that there is no requirement that the
* parser continue to provide useful information after a call to
* fatalError (in other words, a SAX driver class could catch an
* exception and report a fatalError).
