Â
What is the expected behavior when an Entity Container extends another Entity Container and there is an Entity Set with the same name in both?Â
The spec says: "All children of the âbaseâ entity container are added to the âextendingâ entity container." and "An entity set is identified by its name, a simple identifier that MUST be unique within its entity container."
Â
Does that mean this case is invalid?
Â
IIUC, 4.01 adds covariance, i.e., the ability for Structural Types to redeclare Properties defined in the base Structural Type with a subtype. It would be nice if the same were possible for Entity Containers, i.e., if an Entity Container that extends another Entity Container could redeclare Entity Sets with a subtype
