Yup, if I can bring in the term "ancestor" without having to define it, this is the clean way to do it. thx!

Actually, I think "every node except the root has a parent, and no node is its own ancestor" is pretty much a complete definition of a rooted tree. --Alphonse Machiavelli the Warrigal, was it?

Root = own parent was on purpose. Not sure if that screws up any tree math assumptions, but I didn't see any harm in making it so. The real bug (feature?) I noticed is that, as written, two (or more) rules can be each others' parents and detached from the root. -G. (remembering the Switch Switch).

Every existing Rule except the Root has an existing Rule as a Parent, and is a Child of its Parent. The default parent for all children is the Root. Otherwise the Root is its own Parent. And as this is intended to be a tree growing upwards, one cannot go Below the Root. OscarMeyr, making an obscure reference.
