Is there any chance that support for multiple output parameters in rpc-style operations is added soon? As far as I can tell, the following message definition for a server response is perfectly valid with respect to the wsdl specification: <message name="ReadResponse"> <part name="Parameters" type="ns1:TParameters"/> <part name="Error" type="xs:unsignedShort"/> <part name="errorText" type="xs:string"/> </message>

Are there any reasons for not implementing it, that I don't see?

Kind regards, Tim

This would require that the generated C++ method is able to return multiple values... which means either a class/struct, or a std::tuple. Feel free to implement it, I'll review the patch.
