How can descriptions of the Reference property vary when there is only one Reference property listed in Alphabetical listings=>Properties?
I discovered that e.g. Pset_DistributionSystemCommon.Reference has an addition in the description compared to most other uses of the property.
"Reference ID for this specified type in this project (e.g. type 'A-1'), Also referred to as "construction type". It should be provided as an alternative to the name of the "object type", if the software does not support object types and no classification reference to a recognized classification system used. IFC4.3.0.0 DEPRECATION The Reference property is deprecated and shall no longer be used, use attribute Name on the relating type instead.
E.g. 'WWS/VS1', which indicates the system to be WWS, subsystems VSI/400."
While the meaning is fixed globally for props with the same name. There is the possibility for clarifications, comments, remarks, examples, etc. for the usage of a prop within a property set https://github.com/buildingSMART/IFC4.3.x-development/blob/master/docs/schemas/shared/IfcSharedBldgServiceElements/PropertySets/Pset_DistributionSystemCommon.md#reference
