question on xml schema validation with xerces 2

Please enlighten me on this xmlschema Validation using apache xercesimpl.

I want to validate an xml file based on xmlschema. I did the following, the following Java class and the simple xml file.

import org.apache.xerces.parsers.SAXParser;

import org.xml.sax.Attributes;

import org.xml.sax.helpers.DefaultHandler;

import org.xml.sax.SAXParseException;

import org.xml.sax.SAXException;

import java.io.IOException;

// A Simple SAX Application

// Extends org.xml.sax.helpers.DefaultHandler

public class BasicSAX extends DefaultHandler {

// Constructor

public BasicSAX (String xmlFile) {

// Create a Xerces DOM Parser

SAXParser parser = new SAXParser();

// Set Content Handler

parser.setContentHandler (this);

// Parse the Document

try {

parser.setFeature("http://xml.org/sax/features/validation", true);

parser.parse(xmlFile);

} catch (SAXException e) {

System.err.println (e);

} catch (IOException e) {

System.err.println (e);

}

// Start Element Event Handler

public void startElement (String uri, String local,

String qName, Attributes atts) {

System.out.println (local);

}

// Main Method

public static void main (String[] args) {

BasicSAX basicSAX = new BasicSAX (args[0]);

}

<?xml version="1.0"?>

The following is the output. Did I understand the apache documentation wrongly or is this a bug ?

C:\Kiran\test>java -cp c:\kiran\test\xercesImpl.jar;c:\kiran\test BasicSAX note.xml

[Error] note.xml:2:6: Document is invalid: no grammar found.

[Error] note.xml:2:6: Document root element "note", must match DOCTYPE root "null".
