Converting schema in dtd using xsl

Question

Hey all,
I have a problem with an xsl transformtion.
Somewhere on the web I found a xsl-stylesheet to convert schema's into valid dtd's
http://crism.maden.org/consulting/pub/xsl/xsd2dtd.xsl
I've used a program from the JavaTM Web Services Developer Pack to run this xsl on existing schema's but the results are definately nothing like a dtd ... what is this n00b doing wrong .... Heeelp ...
