ifc-element-type

Element, resource and process type definitions: the concrete IfcTypeObject catalogue, generated from the schema, and a writer that stages each type with the schema's rules for it checked first.

The openbim-ifc facade also provides it behind its element-type feature.

Design notes

• create_type and create_supertype take no model and write the catalogue's IFC4X3 layout. create_type_in, create_supertype_in and their *_with_owner_history variants write the model's declared release instead, laid out from its own table; IFC2X3, which requires IfcRoot.OwnerHistory, needs the owner-history variants.
• Every writer refuses a required attribute left unset rather than write $ into it. TypeDraft carries the four type-specific attributes the releases require (IfcDoorType.OperationType, IfcWindowType.PartitioningType, IfcEventType.EventTriggerType, IfcFurnitureType.AssemblyPlace), each token checked against the bound release's enumeration.
• The drafts are #[non_exhaustive]: build them with new() and the setters named after their fields, so a field a later release needs can be added without breaking callers.
