If you want Annex D dispatching rules (that's the semantically significant issue here), then you need to use the pragmas documented in Annex D to have this effect. I would be surprised if there was anything else to this issue. In other words, real time priorities are not an end here, they are simply a means to an end, the end being the proper implementation of annex D features.
