Percent of Parent Entities
API ID: PercentOfParentEntitiesLanguages: Any
Targets: Architectures
Percentage of the parent architecture's entities (recursive) that belong to this architecture.
The parent is the immediate parent architecture. Both counts use recursive entity membership. Useful to see how large this node is among its siblings. Not defined for the root (no parent); returns null for root. Returns null if the parent has no entities.
