But there's a big difference between a data model and an API onto a
data model. The Infoset, for example, isn't an API; you could imagine
many APIs onto the Infoset, which might reveal different parts of the
structure in different ways.

I guess that when I've been talking about a "data model" in this
thread, I've been talking about the Infoset-level data model rather
than the API-level data model. I fully agree that trying to define an
API-level data model would be a complete nightmare, even when you're
in a committee of 3. But agreeing on an Infoset-level data model is
"only" about as burdensome as agreeing on a syntax, at least if my
experience with LMNL is anything to go by.

Cheers,

Jeni
