xsi:nil="true" value can't be parsed

[GoogleCodeExporter]

1. Connect with affected WS (OVH webservice for example):
SoapClient(wsdl="http://www.ovh.com/soapi/soapi-dlw-1.63.wsdl", 
soap_server="axis", trace=debug)
2.Try to invoke logout method:
connector.logout(session)
3.Response xml:

<?xml version="1.0" encoding="UTF-8"?><soap:Envelope 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" 
xmlns:typens="http://soapi.ovh.com/manager" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><logoutRespons
e xmlns="http://soapi.ovh.com/manager"><return xsi:nil="true" 
/></logoutResponse></soap:Body></soap:Envelope>

What is the expected output? 
Properly parsed response.

What do you see instead?

Ah, I forgot and can't edit issue.

Setting strict=False on unmarshall method fixes exception and generates this as 
result

{'return': None}

which I don't know is proper or not here.

Problem is that strict value is hardcoded to True in Client and can't be 
configured without changing Client code.
