### Problem Description

Linking or Importing IFC files using Official 4x3 Schema code → "IFC4X3_ADD2" except for Revit 2024 results in Error:

Figured out that problematic part is Schema Definition in IFC Header "IFC4X3_ADD2"

After changing it to "incorrect" → "IFC4X3" the file is linked without a problem.

### Revit Version

2024.3.x

### IFC for Revit Addon Version

Research direction

Reproduce the reported IFC4X3_ADD2 linking or import failure in Revit 2024.3.x with IFC for Revit 24.3.20, then trace the IFC header schema handling and compare it with the reported IFC4 workaround. Done means IFC files using the official IFC4X3_ADD2 schema link or import successfully without manual header changes.
