* NOTE: Theoretically {@link InstanceValue} is the only metamodel available in Pure.
* Its subtypes are created in Studio so that we can narrow down the types of `values`
* since we don't have powerful type matching like in Pure. Also, due to that, these
* subtypes of {@link InstanceValue} make it easier to transform metamodel back into protocol.
* See https://github.com/finos/legend-engine/blob/94cd0aff3b314e568e830773f7200c8245baa09b/legend-engine-pure-code-compiled-core/src/main/resources/core/pure/protocol/vX_X_X/transfers/valueSpecification.pure#L254
