8.12.3.25.1 Semantic definition
A pre defined item is a qualified name given to a style or font which is determined within the data exchange specification by convention on using the Name attribute value (in contrary to externally defined items, which are agreed by an external source).
The convention on using the Name value is defined at the subtypes of IfcPreDefinedItem and is part of the specification. Corresponding ISO 10303 name: pre_defined_item. Please refer to ISO/IS 10303-41:1994, page 137 for the final definition of the formal standard. New entity in IFC2x2.8.12.3.25.2 Entity inheritance
