Hi,
You really solved my problems.
I am currently playing with the generated bindings and didn't hit any
issues so far. The schemas are large and it will take time to test
everything but I think that it will be OK.

This is correct. After importing all the public modules (that don't start
with _) I can deserialize objects from other namespaces.
Thanks for your help.
Regards,
Vladimir
