Description:
The Javadoc for ErrorListener says:

For transformation errors, a Transformer 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. 

If an application does not register an ErrorListener, errors are reported to 
System.err.


Code to demonstrate the problem:

import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import java.io.*;

public class ErrorListenerTest2
{
   // xsl:template has an invalid attribute (a='1').
   private static String XSL1 = "<xsl:stylesheet version='1.0' 
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>"
                               + "<xsl:template a='1' match='/'>"
                               + "<H1><xsl:value-of select='//title'/></H1>"
                               + "</xsl:template>"
                               + "</xsl:stylesheet>";
                               
   public static void main(String[] args)
   {
        StreamSource source = new StreamSource(new StringReader(XSL1));
        
        try {
            Transformer transformer = TransformerFactory.newInstance
().newTransformer(source);
        } 
        catch (TransformerException e) {
            System.out.println("Error: TransformerException is thrown");
            System.out.println(e);
        }
    }
}

Current output:
Error: TransformerException is thrown
javax.xml.transform.TransformerConfigurationException: javax.xml.transform.Trans
formerConfigurationException: javax.xml.transform.TransformerException: javax.xm
l.transform.TransformerException: "a" attribute is not allowed on the xsl:templa
te element!

The expected behavior is that there is no TransformerException thrown, and the 
error is reported to System.err. You should not see the line "Error: 
TransformerException is thrown". Only the error message is displayed.
