The former contains all meta annotations, including their members, so the type would be recognizable either way. The latter only contains the actual constraint annotation itself (i.e. no meta-annotations) if the constraint is annotated with @Documented. So afaics, from the JavaDoc of a constraint usage site it's not recognizable whether the constraint is generic or cross-parameter (if it's not encoded into the name). Or did you mean something else? --Gunnar
