The DTD doesn't represent data typing; that's the job of
some component that interprets information encoded in XML.
Your overloading of a "flat" namespace makes that hard.
You could have chosen other validatable ways to do this:
Or with namespaces (the "xmlns:" decarations go best in
the DTD, IMHO):
Or even just have the rules that applications must follow
implicitly, based on context (and probably making validation
hard/impossible over time). I'd use an explicit approach,
since context is so easily lost.
