NameDescription
  Mixed-Order Entity
 Mixed-Order Entity is a class of Entitys that is transversal to order levels, defined polymorphically over the universe hierarchy (for every level u).
It is a polymorphic subtype of Entity (declaration: MixedOrderEntity u ⊏⋆ₑ Entity v) and a power instance of Class of Mixed-Order Entity (declaration: ∷ₚₑ), which means that its subtypes may classify entities belonging to any universe level, whereas an Ordered Entity and its subtypes are anchored to a fixed level.
Example:
  Ordered Entity
 Ordered Entity is a class whose sub-types are classifed by a Class of Ordered Entity: It is the power instance of Class of Ordered Entity.
