Don't disagree entirely Foolestroupe about the current conservative view, but do forecast that the practice of notating 'world music' has to change in order to   satisfy a wider audience of players. I may be obsessive, but in my view, if ABC were in Oz they'd be doing it now. The only argument in my mind is the timing. There are already a few Westies giving it some attention, but you'd be surprised how little music East of Istanbul (in abstract formats) exists on the Web. 'Cos it can't using existing conventions.
