Description of the proposal:
The enum values in IfcSimplePropertyTemplate do not have a GUID. I propose to add a GUID for each enum value.
IfcSimplePropertyTemplate
What do we win: We can identify and migrate changed enum values. We can relate all enum values per values to external sources.
What do we loose nothing
Schema impact: low
Instance model impact: All future model files woul have this additional GUIDs
Backwards compatible: depend, on how older systems import files, that contain this addition GUIDs
Automatic migration possible: yes
Additional implications: unknown
