In principle, maybe. But testing a dozen browsers isn't enough here. We simply don't know how much non-browser traffic involves JSON (though we know there are many such interactions), or what representations they are using. We have therefore decided in the 4627bis effort not to say that anything that was previously valid is now invalid. At least, that is what I understand us to be doing. > UTF-32 harms JSON interchange, because Gecko removed all UTF-32 > support throughout the engine (other engines probably did, too, but > I'm too busy to check) and, therefore, XHR responseType = "json" > doesn't support UTF-32. That has about as much weight as "XYZ implementation only supports ASCII, so the use of non-ASCII characters harms JSON interchange" or "ABC implementation only supports 32-bit integers, so the use of decimal points harms JSON interchange." An implementation's self-imposed limitations don't affect the standard. -- John Cowan http://www.ccil.org/~cowan cowan@ccil.org if if = then then then = else else else = if;
