Yes, TBH I'm a little stuck coming up with a name. I want it to be evident that this follows in the footsteps of the Backus-Naur form (for familiarity's sake), but I don't want to do something crass like call it "Ultimate Backus-Naur form" or something. We already have "Advanced Backus-Naur Form" and "Extended Backus-Naur form" and will eventually run out of superlatives...
