Schema - Uncategorized issue for IFC2x4

[dgarg5159]

I am validating an IFC file with IFC4 schema.
The file contains IfcCartesianPointList3D entity which has 2 arguments where data is present in first argument, and second argument is always NULL.

Referred IfcCartesianPointList3D in latest buildingsmart doc also which shows that it will have two arguments (CoordList and TagList).

But BuildSmartTool expects 1 argument for IfcCartesianPointList3D entity.

Could you please help us with the following questions

1. Is it possible to move such cases to the N/A section instead of reporting them as errors?
2. Is there any recommended workaround we can use to avoid this error while still maintaining schema correctness?

It seems you are looking at the documentation for schema version IFC 4X3: IfcCartesianPointList3D where there are two attributes as you have mentioned. However, you indicated that this model utilizes the IFC 4 schema version, which only has one attribute for this entity:

You can also run the schema check locally. If you have python and ifcopenshell installed it's simply python -m ifcopenshell.validate <my_model>. Differences between ifc schema versions are subtle and many, I'd advise to look into code generation from the express schemas if you haven't done already.

we are using below enum set and calling Ifc4 schema only
enum :- Unsupported, Ifc4, Ifc4x1, Ifc2X3, Cobie2X4

but still, we are getting taglist as second argument in IfcCartesianPointList3D.

I referred below cmd which shows that IfcCartesianPointList3D has 2 arguments instead of 1.
py -m ifcopenshell.validate <my_model>

Also, referred one more below command which gives IFC4 as output.
py -c "import ifcopenshell; print(ifcopenshell.open('dummy.ifc').schema)"

Not certain what tool or library you might be using, but it appears to have an incorrect definition of IfcCartesianPointList3D. I don't see any errors with the Validation Service itself.

using xbim.ifc4.interface of version 5.1.0.0 where IIfcCartesianPointList3D has 2 arguments (CoordList, TagList).

Taglist has been added in IFC4.1

@CBenghi any thoughts on this?
