Remember that the big corporations didn't care much about HTTP so it's designers were allowed to work in peace.

I am precisely proposing to go back and study the math -- the parts that work astoundingly well -- so that our newer work is more like calculus than alchemy. It isn't the case that understanding the design of the Web gives one perfect insight into what should or should not be added, any more than understanding the design of a single software system lets you add extensions without ever making a mistake. Nevertheless, you cannot hope to come up with a coherent system *without* understanding the design. And the issues are not always so abstract as relative URIs in namespaces. Recently there was an issue with a sort of abuse of HTTP in XForms. That was a web architecture issue which I believe will be resolved to everybody's satisfaction. Now that I think about it, the whole argument could probably have been short-circuited with a reference to this: * http://www.w3.org/DesignIssues/Axioms.html#state That's the benefit of architectural documents.
