MultiModel and inheriting attributes

I want to do something like this:

[Model('SOURCE')]
[Model('TARGET')]
TModel = class
end;

 [Entity]
 [Table('TBLCUSTOMER')]
TCustomer = class(TModel)
end;

So all entities derived fromn TModel belong to both models. AFAIK attributes are not inheritable, so I am unsure if this will work.

TIA Bernd

Some of they are, but not all:

Model attribute is not one of them, so you have to flag each entity with its explicit Model attribute.
