I have used your schema and XML instance document as posted and then 
applied the following JScript program using MSXML 6:

var schemas = new ActiveXObject('Msxml2.XMLSchemaCache.6.0');
schemas.add('', 'test2009060401Xsd.xml');

var doc = new ActiveXObject('Msxml2.DOMDocument.6.0');
doc.async = false;
doc.schemas = schemas;
doc.validateOnParse = true;

if (doc.load('test2009060401.xml'))
{
   WScript.Echo('valid:\r\n' + doc.xml);
}
else
{
   WScript.Echo(doc.parseError.reason);
}

I don't get any such error as you say you get, unless I change the 
schema to use processContents="strict".

MSXML 6 used here is 6.20.1099.0 (MSXML 6.0 SP2).
