Attestations like ageover* from PID are an important step to allow sharing the smallest amount of information in the verification process. Addressing this requirement by explicitly considering these fields do not scale in the most general case (e.g. what if a new scenario would request an age_over_65 to access specific services (discount, retirement plan etc…). A proper schema to verify derivative predicates can be useful.
