/** \details
  An IfcExternalReference is the identification of information that is not explicitly represented 
  in the current model or in the project database (as an implementation of the current model). 
  Such information can be contained in classifications, documents or libraries. 
  The IfcExternalReference identifies a particular item, such as a dictionary entry, 
  a classification notation, or a document reference within the external source.
  
  Only the Location (as a URL) is provided to describe the place where the information can be found. 
  Also an optional Identification as a key to allow more specific references (as to sections or tables) is provided. 
  The Identification defines a system interpretable method to identify the relevant part of information at the source. 
  In addition a human interpretable Name can be assigned to identify the information subject, such as a classification code.

  \remarks
  This definition may not be instantiated.

  \changes
  
  * IFC4 changes: 
    * Attribute ItemReference renamed to Identification
    * Type of the Location attribute changed from "IfcLabel" to "IfcURIReference"
