This rule checks whether the direct connection property (referenced by reverse connection) has a value type.

Why it matters

While CDF allows value type None as a search optimization for multi-value relations, it’s better to explicitly specify the target view for clarity and maintainability.

Example

If WindTurbine.windFarm has value type None instead of WindFarm, this validator recommends specifying WindFarm explicitly.
