    The containment tree, from IfcModel.spatialTree.

    interface SpatialTree {
        anomalies: SpatialAnomaly[];
        dangling: SpatialDanglingReference[];
        nodes: SpatialNode[];
        orphans: bigint[];
        release: string | undefined;
        roots: bigint[];
    }
    Index
    anomalies: SpatialAnomaly[]
    nodes: SpatialNode[]
    orphans: bigint[]
    release: string | undefined

    The release containers were classified against, e.g. IFC4_ADD2_TC1.
