Here is Boeing take on the matter by the way:

When specifically authorize by the appropriate regulatory authority, approaches may be flown to the following minima:
a published VNAV DA(H)
a published MDA(H) used as a decision altitude.
When either of the above minima are not specifically authorized, use the MDA(H) specified for the instrument procedure.

Note: If using an MDA(H), initiating a missed approach approximately 50 feet above MDA(H) may be necessary to avoid descending below the MDA(H) during the missed approach, if required for the procedure or by the regulatory authority.
So where do I see on my chart if the appropriate regulatory authority allows, me to descend below MDA(H) or not??
For my part this is only if the minimum is listed as a DA on the chart.
