These all sound reasonable, but experience shows that nothing will establish their usefulness except widespread testing over lots of different kinds of loads. For example, if one consistently uses a numeric character reference, it may well be compressed just as tightly as the corresponding UTF-8 character or conceivably better. So if you believe this, implement, release your implementation as Open Source, and let the games begin. -- John Cowan <jcowan@r...> http://www.ccil.org/~cowan "One time I called in to the central system and started working on a big thick 'sed' and 'awk' heavy duty data bashing script.
