This is an old string, BUT in case anyone else comes across it... from what I can tell DTD still has two benefits which XSD does not, namely the inclusion of the ENTITY function which does not exist in XSD. This is a pretty awesome feature which tells the compiler how to process potentially unfamiliar file types by identifying what programs to open to process them.

Also, DTDs are written into the XML spec so they can be written directly into XML documents whereas XSD has to exist as an outside file and connected. Not a big deal especially when using in bigger documents anyway.

I think XSD is still far better and more natural since it uses XML syntax, just wanted to play devil's advocate :)
