Using consumed webservice URL with .svc extension

I am trying to load a consumed webservice (URL) which has a .svc extension. like: https://biztalkservices/operation.svc but I get a error like: An error occurred while parsing the XML Schema in the WSDL document: The global element 'CreateDossierService:CreateDossier' has already been declared.. When loading the webservice URL in SOAPUI it works fine. I understand the error, but find it strange that I only have this error in Mendix and not in SOAPUI. What can cause this ? Thanks!

My guess is that the wsdl document this service returns is not a valid xml document. And maybe soapui succesfully tries to workaround this while Mendix does not. Or it is a bug in Mendix. Could you post the wsdl here?
