IFCWELLKNOWNTEXT reports orphaned Resource Error

[jmirtsch]

I was validating a file with IFCWELLKNOWNTEXT, but a validation error was reported about an orphaned resource. It uses an inverse attribute as it's relationship. Below is my file, if I've misunderstood, please let me know.

Thanks,

Thanks Jon, we never did the schema-level analysis of entities that are referenced only through inverses, we relied only on test data and never found this. We'll fix it asap. The solution is obvious: just add IfcCoordinateReferenceSystem.WellKnownText to the list of inverses that are followed to consider resource usage.

Thanks, that's great. Inverse relationships for this purpose are scarce and I can't think of any others. Certainly I'll raise if I encounter it again.
