I'm wondering how you would use that, and especially if you wouldn't
need the class type as well; you wouldn't need it today as all mapping
is static and so the type can be inferred from the owning
documentBuilder, but we had some plans to make this dynamic (not sure
yet?) so we might need to store the runtime type.
