[Soap-Python] Self referencing object & simpleContent question

[Tsah Zelenka]

Hello,

I need to make a SOAP server implementing an existing WSDL. There are
two things that i don't know how to design in python :
- A complex type whom is referencing to itself
- A simpleContent, for example a string with attributes.

Is there any way to implement them with soaplib? 

Best regards,
T.
