Interface SpatialZoneInStoreParams

IfcRoot.Description, written on every zone of the set. The caller's to use: the viewer puts its zone set's stable id here so a later run can find its own zones after the set has been RENAMED, which LongName cannot survive.

IfcSpatialZone.LongName - the zone SET's name, e.g. "Takt areas".

IfcSpatialZone.ObjectType, which IFC4 REQUIRES when PredefinedType is USERDEFINED (rule CorrectPredefinedType): the enum says "named elsewhere", and ObjectType is where.

IfcSpatialZone.PredefinedType. CONSTRUCTION is what a takt area is.

IfcRelReferencedInSpatialStructure.RelatedElements per zone, by zone index: the expressIds each zone references. An element appears under every zone it touches, straddlers included.
