Subject: [relax-ng] Closure
I have stuck my neck out and claimed that RNG is closed under intersection. Is it? Also Tim Bray wants to know if RNG is closed under set difference. My guess is 'no', but I'd like to know for sure, or know that it isn't known. -- John Cowan <jcowan@reutershealth.com> http://www.reutershealth.com I amar prestar aen, han mathon ne nen, http://www.ccil.org/~cowan han mathon ne chae, a han noston ne 'wilith. --Galadriel, _LOTR:FOTR_
