/** \details
  IfcMaterialDefinition is a general supertype for all material related information items in IFC 
  that have common material related properties that can include association of material with some shape parameters or assignments to identified parts of a component.
  
  There are three ways of assigning materials to a single component or multiple components; they are characterized as:
  * By layer - assigning a material to a layer with constant thickness
  * By profile - assigning a material to a profile with a constant of varying shape along an extrusion
  * By constituents - assigning a material to an identified part of a component shape; the identification is by a keyword rather than by a shape parameter
  
  Each instantiable subtype of IfcMaterialDefinition can have material properties assigned, or have an external classification of its definition. 
  It can be assigned to either a subtype of IfcElement, or a subtype of IfcElementType by using the objectified relationship IfcRelAssociatesMaterial.

  \remarks
  This definition may not be instantiated.
