IfcDiscreteAccessoryType missing "WIRELOOP"Enum but has Pset

The documentation for [IfcDiscreteAccessoryType](https://ifc43-docs.standards.buildingsmart.org/IFC/RELEASE/IFC4x3/HTML/lexical/IfcDiscreteAccessoryType.htm) indicates that it should be used to define "lifting loops" for precast concrete elements and that there is a [Pset_DiscreteAccessoryWireLoop](https://ifc43-docs.standards.buildingsmart.org/IFC/RELEASE/IFC4x3/HTML/lexical/Pset_DiscreteAccessoryWireLoop.htm), HOWEVER there is no corresponding [IfcDiscreteAccessoryTypeEnum](https://ifc43-docs.standards.buildingsmart.org/IFC/RELEASE/IFC4x3/HTML/lexical/IfcDiscreteAccessoryTypeEnum.htm).

Simple oversight? Intentional editing choice?

Start by comparing the linked IfcDiscreteAccessoryType, Pset_DiscreteAccessoryWireLoop, and IfcDiscreteAccessoryTypeEnum entries, then inspect the repository's IFC schema sources for the corresponding definitions. Confirm whether the missing enum value is intentional or an omission; done means the specification decision is recorded and the relevant source and documentation are consistent.
