Good. That's the kind of explanation I am looking for in the docstring.

The comment was also that the sentence is a bit hard to parse because an
ODF doesn't come from an ODF. It might come from a model (or be derived,
calculated, estimated, inferred or assessed from a model, as the case may
be).
