Overview

In a declaration, a Binding has one or more Reference’s. A Binding is for a single ObjectType, normally related to just one Role, and the references (References) to it will normally be the object_type name with the same adjectives (modulo loose binding), or a role name or subscript reference.

In some situations a Binding will have some References with the same adjectives, and one or more References with no adjectives - this is called “loose binding”.
