RE: Capitalism and XML (was RELAX NG Marketing)
Wasn't XML Schema on the boards before RNG? Timing counts. If we stay away from rich vs poor for a moment, I asked a question that consists of "show me the value added by using RNG". Is it: 1. More productive. Can one compose faster, is it easier to learn, does is do what I need to do in the framework? 2. More sustainable. Will a better layered framework using RNG result in information that is more efficient to maintain, reuse, etc.? Cheaper isn't exactly an issue in the tool support. If it translates, then it is reasonable to assume that tools that can support DTDs can be reengineered to support RNG. If John Cowan's AF approach were to be included, we get a kind of inheritance (not really, but). If Schematron techniques are provided, we get co-occurrence validation. A new tool or a better tool is just a C.O.B. issue. So, DSDL looks promising. Now timing is an issue. Legacy builds but Schema legacy isn't that deep yet. Microsoft support is of value and Microsoft listens to their customers. Selling this idea to their customers has value. len From: Nicolas LEHUEN [mailto:nicolas.lehuen@u...] To come back to the RELAX NG marketing issue, I really don't see any domain where XML Schema is preferable to RELAX NG, apart from tool support. And why has XML Schema a better tool support ? Because it is so. Because everybody let the market decide instead of making an decision in good faith. Because XML Schema was proposed by the W3C, which is sponsored by vendors. So vendors influenced vendors, and what we get is a vendor-friendly technology (expensive to implement (even in open-source), expensive to use, with nice formal specs to please nerds and make sure that common people can't get it).
