If you start with first-order propositions when building your model then I think 1NF is required.

If you start out with something else - higher-order propositions maybe - then you aren't required to have 1NF. Whether this is a good idea or not is a different question.

I guess all business data is basically a set of propositions, so your basic choice is whether to go with first-order logic or higher-order logic. I guess you could use some structure other than relations to organise those propositions but I'm not sure what exactly.
