One big reason for XML prototypes to fail to scale up to production systems, AfAIK, is performance (or the cost of buying enough hardware to overcome performance problems). So, I think many organizations are at the stage of buying into XML's (broadly defined to include infoset-oriented technologies such as XPath, XSLT, XQuery, SOAP) mindshare, network effect, ease of implementation, etc. but are blocked by the optimization issues. > > Availability of binary formats leads to temptation > to prematurely optimize, > which will get people into more hot water than > taking a more standards-based, > straightforward approach. Good point! Still, you can't protect people from their own folly. There will be some people in the situation David Megginson described where reducing XML parsing time to zero won't significantly affect overall application performance, but they will use performance optimized techniques anyway. One can only hope that Father Darwin will weed out that meme in the long run :-)
