There are references to non-existent entities, such as step ID 161.

Hm, the same [sample](https://raw.githubusercontent.com/buildingSMART/Sample-Test-Files/master/IFC%204.0/BuildingSMARTSpec/wall-elemented-case.ifc) from Github looks fixed to me. 🤔 It is 4.0 sample file though, before WallElementedCase deprecation. 4.0.2.1 folder is nowhere to be found on GitHub. Wondering if resource files such as examples should be synchronized between site & github

Thanks for checking @claimred! Yes, agreed it would be good to sync them such that no broken example files are published on the IFC docs.

The 4.3 documentation server just pulls the repo and constructs pages from that on the fly

Great! So future git-based documentation will stay in sync! Love it!
