E.11.DSG:10 - Rationale

A Suite is a continuing collection of DPF product series and, once included, its Reference product series. The Reference answers how a reader starts when selection or a cross-DPF question is live. Keeping the Suite collection, Reference belonging, Reference availability, and Reference use separate permits direct use of a known DPF result and permits Reference repair or retirement without rewriting Suite identity.

Progressive detail is not imprecision. The ordinary sentence carries the useful distinction first; exact episteme identity, edition continuity, source use, and stronger relation predicates remain available when they change the claim.
