I don't understand. Are we having different java classes for the subclasses,
or do you mean that we flatten the java classes also?

If we have java subclasses I don't think the component mapping you suggest
will be able to restore the correct type.

If we have one java class, UserInformation, containing all properties from
all subclasses, it will of course work.
