DOCBOOK: novice questions

Hi all,

I am new to the DocBook concepts and am used to use XSL only (till
now)......

However, on the http://nwalsh.com/docbook/xsl/ there are no docs on  how to
apply XSL's to the (docbook)xml files. I succeded in applying the simple CSS
on the simple DTD and thats about it.

Any comments are welcome

greets

SeJo
