Ok, got the picture. Modelling by inheritance.
One comment though. I normally want all my codes to come from a codeset table, hence the descriminator is a foreign key attribute on the master table. But the interface requires me to give a new name for the descriminator (unable to select an existing attribyte). Enterign an existing name will produce duplicate column name in the generated physical model.
