Joe, thanks for your ongoing help scrutinizing HAnim model correctness and quality assurance.
Check question please: does this all look good to you?
The latest diagnostics (X3DUOM loa/parent information, X3D Schematron, X3dTidy) identified a topology flaw in our HAnim2 X3D4 hand models.
Now mostly fixed - some geometry visualization values can be improved for the corrected joints, image attached.
Public offer - does anyone want to fix the visualization geometry?

Further good news, specifications definitely helped confirm this is coming together consistently.
