OK, I think I know where the confusion is coming from...

You write an Schema to describe the data you want. This schema happens
to be written to be Well-Formed XML

You then produce a piece of Well-Formed XML, which includes references
to the schema document. This reference is a URI (A URL, essentially)

There is no intermediate stage.

If you also want to write a definition for the schema-file, it's just a
piece of XML. Thus you either describe it with a DTD, or you include an
appropriate xsi:schmeaLocation

To blow my own Trumpet, you could look at

To promote Eric van der Vlist's work: look at

hope this helps...
