Proxy scenario in SAP PI 7.31

Hi Experts,

Are the  different types to activate proxy scenarios(sender& receiver) in SAP PI 7.31 single stack.

( i )   Adapter type: SOAP    Transport Protocol:  HTTP     Message protocol: XI 3.0 

(ii)    Adapter type: SOAP    Transport Protocol:  HTTP     Message protocol: SOAP 1.1

Does in both ways the webservice should be generated for the function modules in SAP PI 7.31 single stack?

Thanks,

Nithin.
