Sample IFC files not passing the buildingSMART validation service

[Philipp-p]

I tried two of your sample files and uploaded them to the buildingSMART validation service. Unfortunately, they failed the validation, and I am wondering if this is negligible or not, especially in the case of an issue with the IFC schema itself.

For Duplex_A_20110907.ifc the rule verification fails on a lot of case according to

GEM111 - No duplicated points within a polyloop or polyline
The rule verifies, that all the polyloops and polylines will have no duplicate points, unless it's the first and last point of a closed polyline.
In that case, it must be identical by reference (referencing the same instance), not just having the same coordinates.

and twice on

Feature: GEM002 - Space representation

 The rule verifies that all IfcSpaces have a correct Body shape representation.

Scenario: Agreement152_1 - Agreement that all spaces must have a body shape representation

  Given An IfcSpace
   Then There must be one Body shape representation
    And The Body shape representation has RepresentationType "SweptSolid, Clipping, Brep"

In the case of Clinic_Structural.ifc we have problems with IFC schema itself:
