Abstraction for models of elements which must be qualified by an instance to order to be evaluated, including:

- `Attribute`s (a Qualified `Value`),
- `Method`s (a Qualified `Function`),
- MemberClass (`member classes`) (a Qualified `Class`) and,
- MemberClassConstructor (`member constructors`) (a constructor of a Qualified `Class`).

To qualify a `Qualified` metamodel instance in a type-safe way you simply invoke it. Alternatively use `bind()` if the qualifying instance's type is unknown until runtime.

Methods
`bind` | Source Code `shared formal Kind bind(Object container)` Type-unsafe container binding, to be used when the container type is unknown until runtime. This has the same behaviour as invoking this `Member` directly, but exchanges compile-time type safety with runtime checks. Throws `IncompatibleTypeException` If the container is not assignable to this member's container
