why is this not validating?

[scorpion]

I have this problem that an xml instance is validated correctly
by xml tools, but not with my simple code, by setting the
validating flag to true.

--------------- Schema -----------------------------
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema elementFormDefault="qualified" xml:lang="EN"
targetNamespace="http://www.mydomain.com/demo/Test"
xmlns:test="http://www.mydomain.com/demo/Test"
xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xs:element name="TestO" type="test:TestType"/>
<xs:complexType name="TestType">
<xs:sequence>
<xs:element name="Name" type="xs:string"/>
<xs:element name="Value" type="xs:integer"/>
</xs:sequence>
<xs:attribute name="id" type="xs:ID"/>
</xs:complexType>
</xs:schema>

---------------- Instance ----------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<test:TestO xmlns:test="http://www.mydomain.com/demo/Test"
xsi:schemaLocation="http://www.mydomain.com/demo/Test
file:///home/csp/workspace/test-java/test.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" id="example-ncname">
<test:Name>string</test:Name>
<test:Value>1</test:Value>
</test:TestO>

This is validating correctly using XMLBuddy, XMLSpy, etc. But when
I try to do with the following code

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setValidating(true);
DocumentBuilder db = dbf.newDocumentBuilder();
db.setErrorHandler(new SimpleErrorHandler());

Document document = db.parse(new
File("/home/csp/workspace/test-java/test.xml"));

It's reporting the errors

org.xml.sax.SAXParseException: Document root element "test:TestO", must
match DOCTYPE root "null".

What's wrong with that code?

TIA

Forget about this. Had to use "dbf.setAttribute()" instead.
