IfcPreDefinedPropertySet is a generalization of all statically defined property sets that are assigned to an object or type object. The statically or pre-defined property sets are entities with a fixed list of attributes having particular defined data types.

IfcPreDefinedPropertySet's can be assigned to objects and object types but do not have a defining property set template.
