/** \details
  The distribution element IfcDistributionControlElement defines occurrence elements 
  of a building automation control system that are used to impart control over elements of a distribution system.
  
  IfcDistributionControlElement defines elements of a building automation control system. 
  They are typically used to control distribution system elements to maintain variables such as temperature, 
  humidity, pressure, flow, power, etc. 
  The three general functional categories of control elements are as follows:
  * Impart control over flow control elements (IfcFlowController) in a distribution system such as dampers, valves, or relays, typically through the use of actuation (IfcActuator).
  * Sensing elements (IfcSensor) that measure changes in the controlled variable such as temperature, humidity, pressure, or flow.
  * Controllers (IfcController) typically classified according to the control action they seek to perform and generally responsible for making decisions about the elements under control.
  
  Since IfcDistributionControlElement and its subtypes typically relate to many different distribution flow elements (IfcDistributionFlowElement), 
  the objectified relationship IfcRelFlowControlElements has been provided to relate control and flow elements as required.
  
  The key distinction between IfcDistributionFlowElement and IfcDistributionControlElement is whether it is internal or external to the flow system, respectively. 
  For example, the distinction between IfcFlowMeter (subtype of IfcDistributionFlowElement measuring a flow quantity) 
  and IfcFlowInstrument (subtype of IfcDistributionControlElement measuring a flow quality), is based on this principal. 
  A physical device that connects within the flow system in which it measures (having inlet/outlet pipes for the measured substance) 
  follows the IfcDistributionFlowElement hierarchy (and therefore IfcFlowMeter which measures the flow internally). 
  Otherwise, if it monitors/controls but does not connect inline within the flow system (it is external or is a component of another device), 
  then it follows the IfcDistributionControlElement hierarchy (and therefore IfcFlowInstrument which can display various attributes through connected sensors).

  \changes
  
  * IFC4 changes: 
    Attribute ControlElementId attribute is deleted; replaced by classification usage. 
  Ports are now primarily defined using IfcRelNests to enable definition of ports at type definitions (both forward and backward compatible), 
  provide a logical order, and reduce the number of relationship objects needed. 
  The relationship IfcRelConnectsPortToElement is still supported, however is now specific to dynamically connected ports.
