WSDL not getting validated

I have created the following WSDL file. When I try to validate it using eclipse, it gives me the following warning

"WS-I: A problem occured while running the WS-I WSDL conformance check: org.eclipse.wst.wsi.internal.analyzer.WSIAnalyzerException: The WS-I Test Assertion Document (TAD)document was either not found or could not be processed.The WSDLAnalyzer was unable to validate the given WSDL File."
