Clause 5.10.2.5 uses permissive ("should") wording for narrowing a returned Context Source Registration to the `information[]` entries that match the discovery filter on `GET /csourceRegistrations`. Several `QueryContextSourceRegistrations` fixtures assert the **full, unfiltered** `information[]` array, so a broker that honours the "should" (removes the non-matching entries) fails them. Request: confirm the intended behaviour and align the fixtures — either accept the filtered `information[]`, or relax the assertion so both forms pass.
