Validating a xml schema (xsd file)

Question

Hi,
I was wondering - my program should accept schema files and before doing whatever it does with them I want to put them through a validation and present errors if any.
I wasn't sure what is the right way to go about this - I know how to set up a validating parser with my own ErrorHandler and retrieve error info for simple xml files and xml schema instances, but how do I set up the parser to validate a schema definition?
My first idea was to validate it like I would validate any schema instance, since xsd files also have their own schema definition, but that seems kind of funny, since obviously the parser already knows what a schema definition should look like.
Has anyone done this?
Thanks,
Uri.

Try something like this??
DocumentBuilderFactory DBF = null;
try
DBF = DocumentBuilderFactory.newInstance();
catch (Exception fce)
// Set various configuration options
DBF.setValidating(true);
DBF.setNamespaceAware(true);
DBF.setIgnoringComments(true);
DBF.setIgnoringElementContentWhitespace(true);
DBF.setCoalescing(true);
DBF.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaSource", new File(Filename));
DBF = DBF.newDocumentBuilder();
DBF.setErrorHandler(this);
DBF.setEntityResolver(this);
catch (Exception pce)
blah blah blah blah....
I hope this is what you were looking/asking for... I could be way off base here 8-))
