(and >the same kind of gains for data storage) The world may have a place for binary XML, but the above is not an argument for it. First of all, an argument that unpacking a binary format (particularly on a machine whose binaries are different and you have to bit-swizzle) is significantly faster than XML parsing a la expat or MSXML, needs to supported by actual empirical data rather than by assertion. And suppose, as a thought experiment, that this were true; if you were to speed up the XML parsing/generating part of an XML-using application, how much would that speed up the whole application? You'd need to know what proportion of its time it spends parsing/generating XML. In some apps, this proportion is going to be very small. As for the data storage volume issue, uh, isn't the world awash in admirable compression technology that works pretty well on most data formats, and particularly well on redundant textual stuff like XML? Absent some good strong empirical evidence, neither processing nor storage cost are a priori arguments for going binary. -Tim
