Aphatia,
I am going to reply only to you in this thread, exactly because you are not a mathematician, which is limited to the western school of thought.
You are asking for a rule.
Please read again
http://www.geocities.com/complementarytheory/UR.pdf in order to see how the concept of rule is nothing but a particular case of hyper-formalism, where
No form has a meaning of its own.
MAFs are simply the Relation\Element Interaction (without any meaning) that can be found under any given cardinal.
You, the mathematician take Relation\Element Interaction (REI) and invent your researchable game, by giving it meaning where rules already have meaning.
By standard formalism, Relations have meaning (the hold the rules) where Elements can be replaced by any other elements that obey the invented\discovered rules.
Higher-order logic is a particular case of Universal Reasoning (Hyper-Formalism) because Higher-order is based on some particular asymmetric MAF.
Again, Relation\Element Interaction is not a dualistic framework exactly as a tree with a one trunk and infinitely many branches (that are related to each other by infinitely many distinct ways, where each way is both general and particular case of the entire tree) is not a dualistic framework.
You still don't get how Hyper-formalism's natural transparency of any meaning, is the best detector of being aware of any meaning (rule, etc...) that is given by the mathematician.
The form without any meaning is the best way to avoid hidden assumptions during mathematical developments.
