XML DTDs have always been able to refer to and build on other XML DTDs.
XML schemas are marginally better than DTDs at abstraction but I think
that both have a fatal flaw in that their abstraction mechanisms only
work on the tree data structure and do nothing for links. What real
application does not rely on links?
