Tree-trickery may not be possible in the context of stream based processing. Sometimes "minimizing the decls" isn't an achievable goal. You may end up adding a few decls in case they're needed later, but it turns out they aren't. "Minimizing the decls" is a global optimization problem, or an interesting way to compare policies. The problem may not need to be solved; even when people look at the documents directly, it's not the same as "easy to understand" (which is an individualized issue, also very context-dependant, that sometimes values redundancy). > Finally, I don't think variable-scoping is a useful comparison for > namespace-scoping in XML documents. I was going for accuracy in explaining the name binding rules. Actually using those names is a different issue. > Variable scoping is nicely contained by the logic of program > flow, while namespace scoping may be much more arbitrary. I guess I don't see that. They're both used to characterize data; the scoping requirements aren't very different. (The same values can be found in many variables ...) Or are you maybe suggesting that most documents don't have lots of namespaces in use, while most programs have many variables? - Dave
