Syntax Editor Not Recognizing Hierarchy Rule Functions

I noticed in an Arc TI editor that Hierarchy rules functions like HierarchyCount, HierarchyIndex, and HierarchyN don’t appear to be recognized. I’m on Arc 3.1 with TM1 11.8.00900.3. Can this be added to the syntax validation? I’d prefer to use this than looping through hierarchy dimensions.

Nevermind. I see that it says these are valid only in TM1 rules.
