When I created this issue pre-Bentley it made more sense. Now this seems like a big issue that'll probably get pushed past GTM.

I had one required property, but we removed it due to issues Sean was having in the tiler. I believe it was the category name. Now nothing is required.

I can see that validity of nothing being formally required at GTM until we nail down user cases or really look at the obvious candidates like elementId. But if we want a true intermediary format, then we might need to find analogs in IFC and require those, too. This also ties into whether or not we swap out the intermediary format.

Fundamentally, I think it needs a lot of work investigating the intermediary format before we lock this down. That may even entail making the specification of required moot.
