hi,

that looks like a bug if it is the case however i was not able to access 
imported WSDL at all, from outside hp.com it is not possible to read:
http://mip.esr.hp.com/wsdm/wsdl/MUWS.wsdl
(specified in WSDL in          <xsd:import 
namespace="http://docs.oasis-open.org/wsdm/2004/04/muws-0.5/schema" 
schemaLocation="http://mip.esr.hp.com/wsdm/wsdl/MUWS.xsd" />)
