Thanks for the tips, @Tattoo. You have a good idea for detail. I will investigate and update the guide based on your info.
NoOcclusion isn't exactly in an .xml file; it's in the combined files in MeshCache.zip/models_*
E.g. MeshCache.zip/models_bridge_asphalt_double
Skimming through my property list, here's what I couldn't figure out (not including what you've already addressed):

- Divergence
- Perpendicularity
Model Class XML (Physics)
- NightLightingShadowsAllowCap
- NoSoftContacts
- NoSoftImpulse
Model Flares
- SizeAtDay
- Reflections
... and Lights
- CreateSuperLight

Plant Mesh XML (Material)
- OcclusionIntensity (only partially understood)
- OcclusionRadius (only partially understood)
- IsFoliage (only partially understood)
Plant Class XML (PlantBrand)

Dang. It's kind of embarrassing when I list them all together.
