Hi Will, I'm confused by exactly where the problem comes in, though it looks to me like you may not be representing the relationships between the classes properly in the binding. Can you show the document that gives you the unmarshal error? From the error message, I'd say the runtime is seeing a PAYLOAD element where it expects to find an INNERPAYLOAD1 or INNERPAYLOAD2 element (an instance of InnerPayloadImpl).
