normally this is the case but since your Persoon object inherits from
Entity, the "naam" attribute is inherited from Entity and is still
present. The case of a subclass trying to "move" the column which
is named differently on the base class has not been addressed as of
yet (which basically means, it doesn't work). It would also be a
little tricky to make it work within SA since if you set different
data on Persoon.naam and Persoon.achternaam, that would be kind of
ambiguous. There's no real way for Persoon to not have "naam" at all
since its a subclass of Entity and from a Python point of view will
inherit all attributes.
