question: public void error ( SourceLocator srcLctr , String msg , Object args [ ] , Exception e ) throws TransformerException { String formattedMsg = XSLMessages . createMessage ( msg , args ) ; ErrorListener errHandler = m_transformer . getErrorListener ( ) ; if ( null != errHandler ) errHandler . fatalError ( new TransformerException ( formattedMsg , srcLctr ) ) ; else throw new TransformerException ( formattedMsg , srcLctr ) ; }
target:  Tell the user of an error, and probably throw an exception.
