public interface ERElement extends IdentifiableElement, ModelElement
An interface for identifiable entity-relationship (ER) elements of the model.

This serves as a common type for core model elements like Resource, Facet, IsRelatedTo, and ConsistsOf. It extends IdentifiableElement and ModelElement, and adds a property to retrieve the contexts in which the element exists.
