Hi Holger, 

this is issue 10 now. [1]

Just to clarify the terminology, I have to note that in WSDL 2 terms, 
a service is an instance of a single interface which can extend multiple
other interfaces. You are practically correct, but the attribute
"interface" on <service> can still only have a single value, which might
have caused confusion. 8-)

Best regards,
