I'm putting plans together for a mission style bookcase, stackable barrister-ish construction, white oak. The case ends will be frame and panel. My question is what a true mission style look is wrt the panel-side edge on the rails/stiles. I've seen many examples that are just a square edge vs round/chamfer/etc, and that is what I've come to believe is mission style. However I do find some examples claiming mission style with a round and ogee treatment. The square edge is a dust catcher and harder to clean corners of the panel. So I'm caught between wanting true mission style but also practical convenience.
So, what is the consensus view on mission style panels?
Thanks!
