DTD Question

You are not missing anything tremendously obvious, although you might want to take a look at the namespaces proposal (http://www.w3.org/TR/WD-xml-names).  This allows scoping, although not as easily as in your average programming language.  (Sorry -- I forgot to mention it before.)

I'm not convinced that having only global variables dooms a language.  It might make it more difficult to use, but I don't think there are any programs that can be written with locally scoped variables that can't be written with only global variables.  I'm also not convinced that document languages have the same requirements as programming languages.  HTML might not be the best document language in the world, but it is limited to global variables and it has enjoyed a rather modest success ;)

Many thanks. I was afraid of that.

It seems that trying to force a "flat" typing paradigm onto
somethings that is inherently nested is doomed. It is like
having a programming language where all variables are
global (they cannot be scoped to specific functions).

I'm new to all of this and trying to make sense of it.
Am I missing something tremendously obvious?
