Yes, I sorry. It is the other way around.

Inferring an xml instance from an xml schema is not trivial, since an xml schema can contain infinite paths.
And it is not possible to automatically infer this at a unmediated construction of an xml instance.

I have not seen any python tools that supports this action.
Sorry for the inconvenience and good luck in your search.
