      Unfortunately the identifying relationship is not always possible. From my understanding to make the identifying relationship work you have to make the foreign key part of the primary key. We have a scenario where the child has derived types. The derived type tables have the child key but do not have the parent key and so modifying the child to use the parent key in its own primary key breaks the inheritance. Presumably this would also be a problem if the child had children.
