/** \details
  This entity is an objectified relationship that defines the relationship 
  between a system and the sites, buildings, storeys, spaces, or spatial zones, it serves. Examples of systems are:
  * Building service systems (heating, cooling, waste water system) represented by instances of IfcDistributionSystem;
  * Building systems (fenestration, shading) represented by instances of IfcBuildingSystem;
  * Zones as collection of logically grouped spaces represented by instances of IfcZone
  * Idealized structural analysis systems represented by instances of IfcStructuralAnalysisModel.

  \remarks
  The name IfcRelServicesBuildings is a known anomaly, as the relationship is not restricted to buildings anymore.

  \changes
  
  * IFC2X_FINAL changes: 
    The data type of the attribute RelatedBuildings has been changed from IfcBuilding to its supertype IfcSpatialStructureElement with upward compatibility for file-based exchange.
  * IFC4 changes: 
    Type of the RelatedBuildings attribute changed from "set[1:?] of IfcSpatialStructureElement" to "set[1:?] of IfcSpatialElement".
