while considering the definition of the referenced CRS [32760](https://epsg.io/32760):

I wonder:
# Question
Shouldn't the unit of the `IfcProjectedCRS.MapUnit` be a metre, and not a millimetre?
This applies to all example files [here](https://github.com/buildingSMART/Sample-Test-Files/blob/5016207e14159f2fcf60d6f4dddfedfb7d2e0994/IFC%204.3.2.0%20(IFC4X3_ADD2)/PCERT-Sample-Scene/).

Research direction
Start with the linked Infra-Bridge.ifc lines 22 and 25 in the PCERT-Sample-Scene directory, compare the MapUnit with EPSG:32760, and inspect the other example files linked in the issue. Confirm the expected unit and update every affected PCERT example, then verify that their georeferencing metadata is consistent.
