Definition from IAI: The IfcControl is the abstract
generalization of all concepts that control or constrain Products or Processes
in general. It can be seen as a specification, regulation, constraint or other
requirement applied to a product or process whose requirements and provisions
must be fulfilled.
EXAMPLES for Controls are space program, construction
guides, etc.
It is defined in the IfcKernel but will be reused and specialized
in other schemas.
