flatness of the derived median plane question

[Andrew T]

Can flatness of the derived median plane be used as shown per the attached image?

If yes, then which view should points "M" and "N" be shown in? I have these points in multiple views for the sake of clarity of my question.

This is a stamped part. It is my feeling that flatness of the derived median plane captures the essence of this part better than flatness of a surface. However, if I cannot us FOTDMP in this manner I would need to call out flatness of a surface for the side that has the two tabs bent down. This would be the bottom surface, with the words "SECTION A-A" nearest.

Thank you!

Yes, the flatness of median plane can be specified this way however the "M between N" specification is not required...
