Crate ifc_occurrence 

Built element and distribution occurrence classes.

A type definition says what a pump is; an occurrence says that one particular pump sits here, in this system, with this tag. This crate authors the occurrence side and enforces the link between the two: the schema pairs each occurrence class with exactly one type class, and a mismatch is refused rather than written.

The catalogue in table is generated from references/ifc-spec/ifc4x3-add2/IFC4X3_ADD2.exp by scripts/gen-occurrences.py; create and create_with_owner_history are the writers. They write the model’s declared release, laid out from its own table, not the catalogue’s IFC4X3 row.
