Schema just allows more extensive validation and better support of XML
(DTDS are pretty SGMLish). Some advantages are:
* Support for namespaces
* Rich datatype set (booleans, the usual set of numbers types,
dates, URIs, intervals, ...)
* User defined types.
* "Inheritence" which is really more like refinement.
There's more, but basically XML schema is a better DTD.
