/** \details
  An IfcConstraint is used to define a constraint or limiting value or 
  boundary condition that can be applied to an object or to the value of a property.
  
  Constraints can be subdivided into user-defined constraints and system-defined constraints. 
  User-defined constraints are applied by a user and are restricted to high-level definitions such as object properties. 
  System-defined constraints can apply to any object attribute, are typically defined by an application 
  to enforce data validation or parametric behavior, and are intended to be enforced 
  by applications but not to be directly editable by an end-user.

  \remarks
  This definition may not be instantiated.

  \changes
  
  * IFC4 changes: 
    * Type of the CreationTime attribute changed from "IfcDateTimeSelect" to "IfcDateTime"
    * Inverse attribute ClassifiedAs renamed to HasExternalReferences
    * Type of the ClassifiedAs inverse attribute changed from "SET OF [0:?] IfcConstraintClassificationRelationship FOR ClassifiedConstraint" to "SET OF [0:?] IfcExternalReferenceRelationship FOR RelatedResourceObjects"
    * Inverse attribute RelatesConstraints to PropertiesForConstraint
    * Type of the inverse attribute RelatesConstraints changed from "SET OF [0:?] IfcConstraintRelationship FOR RelatingConstraint" to "SET OF [0:?] IfcResourceConstraintRelationship FOR RelatingConstraint"
