Where are ALL the displaygroupobject leaf methods documented?

I've noticed that the online documentation hasn't been updated to include all possible leaf methods for the displaygroupobject.

e.g.

leafType options does not include leafType=ALL_KINEM_COUPLING

LeafFromConstraintNames is not documented as an option.

 

Ultimately I'm trying to create a tool that will display elements that share nodes.  

 

Thanks,
