How is that better than having a Doctype root if subdocs were inlined? I can understand it not pointing to anything but only in the context of how FPIs work in Doctypes. So what am I to assume if I see a dt: prefix that has a classID in the ns attribute, and another that *appears* to point at a schema of some sort? > nor > is it guaranteed that all names with the same prefix are defined by > the same schema (or by any explicit schema). Outside a formal registry, I don't think that guarantee would work anyway as the long long long debates on URI/URN/URLs showed. John Cowan writes: >Not necessarily.

How is that enforced or proven? Yes, I watched the namespace debates. It is hard to tell what the namespace is good for if the ns attribute is essentially a valid but purposeless bit holder. Ok, it *indicates* a scope. ???? I realize something subtle is being defined, but maybe it is too subtle to be useful for much. Consider me standing up to type... If DCD isn't clearer than namespaces, than the HyTime drubbing goes down as one of the great crimes of critique. Precision aside, if the concepts and tools are harder to figure out than SGML and HyTime, this time next year I won't be the only one with a sore bottom. Wired and XavierMcLipps are watching. -) Ah so... back to reading the XML pages at www.microsoft.com which for some reason are understandable and have working code with which to test them.
