Hi arkadiyb,

unfortunately, there's no way. SOAP::WSDL is aimed at document/literal web services complying to the WS-I standard profile - and supporting SOAP encodings is way out of it's scope.
If your WSDL isn't too complex, you'll probably get along well with SOAP::Lite, which is targeted at rpc/encoded webservices (SOAP encodings are usually used in rpc/encoded web services). You may also want to try XML::Compile::SOAP.
