Description copied from interface: AnnotationAccessor

Store a key or name for the accessor to reference when it attempts to obtain the value of an object. Different implementors will have different uses for the key. For example, it could be the name of the feature that should be returned. It could also be the name of a property to invoke on the Annotation object.
