//! The generated occurrence catalogue.
//!
//! Source: `references/ifc-spec/ifc4x3-add2/IFC4X3_ADD2.exp`, via
//! `scripts/gen-occurrences.py`. Do not edit by hand.
//!
//! # Two rules, and why the second one needs the type catalogue
//!
//! `CorrectPredefinedType` is the familiar one: USERDEFINED
//! without `ObjectType` names nothing.
//!
//! `CorrectTypeAssigned` is stronger and has no analogue on the
//! type side. An occurrence may be typed by at most one type,
//! and that type must be the one class the schema pairs with it:
//! an `IfcPump` takes an `IfcPumpType` and nothing else. The
//! pairing is a fact about the schema, so it is recorded here
//! rather than left to the caller.

/// One occurrence class: its slots, enum, and permitted type.
