Wsdl 2.0

Hi ,
I have being using soap ui for testing the webservices which i have created ,
i am facing an issue whien i am trying to test wsdl2.0 artifact , i do see an error :

WSDLException (at /wsdl2:description): faultCode=INVALID_WSDL: Expected element '{http://schemas.xmlsoap.org/wsdl/}definitions'.

Is wsdl2.0 not supported as part of soap-PRO 4.5.0 ? if yes ,then any reason for not supporting it ?

Best,
Raghavan
