perhaps those approaches for which a CDFA can not be flown will still be published with a MDA(H), with the 200m/400m added on already?
Yes - the 200m/400m requirement only goes for flying to CDFA minimums using non-CDFA techniques.
b) I need to produce training materials for my instructor colleagues and my students which is clear, unambiguous and correct.
Good on you! The flight school I went to never had much of that, not to mention the fact that it was based abroad, so I had to more or less learn the procedures from scratch again when starting my first job. Of course, since then there's been numerous changes, but I guess staying on top of that is just part of airmanship. Again, good on you for taking the time and effort to investigate for your students!
(And what approach chart did you want to see? We got them in "all shapes and colours" here, I'm sure I can find something useful.)
