I think the point is that although CDFA NPAs are now industry standard - as promoted by the FSF ALAR programme and through JAR OPS NPA 41 (which is now incorporated in EU OPS-1) it requires the individual approval of NPAs by the NAAs to use the MDA as a DA. Generally operators use MDA+50 ft as a company DA to avoid penetrating the MDA. However, some MDAs are being approved as DAs and in this case descent below MDA is allowed. It must be clearly approved though. One thing the new Jep plates show - without any approval implicit - is the CDFA profile encoded into the Nav database, along with the waypoint names. Very useful!
