So it seems your question is more how do I relate an XML source file to 
a schema so that it is validated against that schema.
There are ususally two ways to do that, you can use the 
xsi:schemaLocation attribute in the source XML file to list the 
namespaces and schemas that are relevant to the XML file and then a 
parser should be able to load the schemas and perform the validation.
The other way doesn't require editing the XML source file and sticking 
attributes in there to list the schemas but simply use a parser 
dependant API to tell the parser which schemas to load for which 
namespace before you ask the parser to perform validation.
MSXML 4 has an API to do that, you usually load the schemas into a 
schema cache and associate the cache with the XML document object before 
you call the load method:

var schemaCache = new ActiveXObject('Msxml2.XMLSchemaCache.4.0');
schemaCache.add('http://example.com/2004/05/gods', 'test20040501Xsd.xml');

var xmlDocument = new ActiveXObject('Msxml2.DOMDocument.4.0');
xmlDocument.async = false;
xmlDocument.validateOnParse = true;
xmlDocument.schemas = schemaCache;

var valid = xmlDocument.load('test20040501.xml');
if (valid) {
   alert('Document is valid.');
}
else {
   alert(xmlDocument.parseError.reason);
}
