Validation with external-noNamespaceSchemaLocation works with DTD, not with xsd schema

Hi all,

Validation (SAX and DOM) with external-noNamespaceSchemaLocation works with 
DTD, not with xsd schema (xerces 2.6.1).

The following code bails out with an error on xsd schema but works fine with 
DTD. Problem is that with xsd, it does not realise that it has to deal with 
xsd, hence the error as can be seen below.

Is this a bug or what has to be changed in the code to get this working?

code
----
import org.apache.xerces.parsers.DOMParser;
import org.w3c.dom.Document;

class validate {
	public static void main(String[] args) {
		try {
			DOMParser aParser = new DOMParser();
			aParser.setFeature
("http://xml.org/sax/features/validation", true);
			aParser.setFeature
("http://apache.org/xml/features/continue-after-fatal-error", false);
			aParser.setFeature
("http://apache.org/xml/features/validation/schema-full-checking", true);
			aParser.setProperty
("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",
					args[1]);
			aParser.parse(args[0]);
		} catch (Exception e) {
			System.err.println("Exception caught in main: " +e);
			System.exit(1);
		}
	}
}

compile
-------
javac -classpath xercesImpl.jar:xmlParserAPIs.jar validate.java

files used in the next tests are from Xerces-J-bin.2.6.1.tar.gz from data 
directory

correct run with DTD
--------------------
java -classpath .:xercesImpl.jar:xmlParserAPIs.jar validate personal.xml 
personal.dtd

incorrect run with xsd schema
-----------------------------
java -classpath .;xercesImpl.jar;xmlParserAPIs.jar validate personal-
schema.xml personal.xsd

[Error] personal.xml:2:11: Document is invalid: no grammar found.
[Error] personal.xml:2:11: Document root element "personnel", must match 
DOCTYPE root "null".

As mentioned before this code is not aware that it has to deal with xsd 
schema instead of DTD. How can this be fixed since the code example is in a 
lot of tutorials on the net.

Thanks,

Pander

Have you tried enabling the
"http://apache.org/xml/features/validation/schema" feature?
