You can use either an XML Schema or a DTD to specify vality and default
rules for a type of XML document. Since XML Schema is basically a
superset of DTD, you can (if you're careful) write XML Schemas and DTDs
that define exactly the same type of document. In fact tools like XML
Spy can convert a DTD into the equivalent schema.

Once you've defined your document type you can then write an XSLT
transform to process documents of that type. In other words if
myMusix.xsd is your schema, and defines XML docs with elements like
<music/>, <bar/> and <note/>, then your XSLT can assume that those
elements will be in its input.

So the design of the stylesheet depends on the document type, but not on
the choice of DTD or XML Schema for defining that type. 

I hope this helps!
