5//! Relationship attribute slots per `IfcRelationship` subtype (issue #4205).
6//!
7//! DO NOT EDIT — generated by `scripts/generate-server-relationship-slots.mjs`
8//! from `@ifc-lite/parser`'s schema-derived `relationship-schema-slots.ts`
9//! (the same source the in-browser/WASM columnar parser resolves relationship
10//! slots against), so the server-parse path reads `RelatingX`/`RelatedY` at
11//! IDENTICAL attribute positions.
12//!
13//! Lookup key is the UPPERCASE STEP type name. Indices are ABSOLUTE attribute
14//! positions (i.e. `relationship-schema-slots.ts`'s 0-based-after-root index
15//! plus the shared 4-attribute IfcRoot+IfcRelationship prefix), matching what
16//! `DecodedEntity::get_ref`/`get_list` expect.
17//!
18//! `54` of `55` schema-derived concrete
19//! `IfcRelationship` subtypes resolved a slot plan. `IFCRELASSOCIATES` did not: it has
20//! no `RelatingX` attribute of its own in ANY bundled schema version (an
21//! abstract supertype that IFC2X3's bundled registry happens to mark
22//! non-abstract — see the generator script's header for the full
23//! explanation). It is intentionally absent from this table; no concrete
24//! STEP file instantiates it directly.

26/// One relationship type's relating/related attribute slots.
27///
28/// `relating_is_list` is true for exactly one type as of writing —
29/// `IFCRELDEFINESBYPROPERTIES`: `RelatingPropertyDefinition` is typed
30/// `IfcPropertySetDefinitionSelect`, whose second alternative
31/// (`IfcPropertySetDefinitionSet`) is a defined `SET` of entities, written
32/// inline as `(#20,#21)` rather than as a single `#id`. Reading it with
33/// `get_ref` alone returns `None` for that shape and silently drops the
34/// whole relationship — the same failure mode `related_is_list` already
35/// guards against on the other slot.
