I wonder what’s the difference between `id` and `identifier` in the OrderLineItem object.

Yes, they have different values, but what are they referrencing / what does reference them?

I mentioned when working on discount-information that in the `payload` if it is discount-data there’s an entry `composition` which contains the discount-composition referring to `identifier`.
