[OAI-implementers] validation of OAI response

hi and thanks,

did you import the oai_dc.xsd in the OAI-PMH.xsd? I can only get the
jOAI response to validate if I add the oai-dc XMLschema to OAI-PMH.xsd using

	<import namespace="http://www.openarchives.org/OAI/2.0/oai_dc/" 

This is fine for this purpose here, but I'm wondering what a generic 
solution would look like. Since any namespace can occur inside 
<setDescription> I cannot import them all in OAI-PMH.xsd.


P.S the incorrect xml doc in my email as due to my messing around with 
the code. jOI does of course provide correct xml.
