Marker interface for a member element of a `ClassModel`. Such an element can appear when traversing a `ClassModel` unless otherwise specified, be supplied to a `ClassBuilder`, and be processed by a `ClassTransform`.

`AccessFlags`, and `ClassFileVersion` are member elements of a class that appear exactly once during the traversal of a `ClassModel`. `Superclass` and `Interfaces` may be absent or appear at most once. A `ClassBuilder` may provide an alternative superclass if it is not defined but required.
