There are several possibilities. You can hand modify the implementation
classes or interfaces with what you need. You can define operations to
do the equivalent; it's possible to suppress their visibility in the API
(see EcoreUtil.setSuppressedVisibility for how the annotation looks). Or
you could use generics, e.g., AbstClass has a parameter <T extends
Identifier> and make the reference of type T; then in ConcrClass you can
