DOCBOOK-APPS: Changing the header of an article

Hi

I'm writing a couple of articles for the company. I'm using "out of the
box" xsl stylesheets with xsltproc and fop.

Right now the layout of the page is like this:

___________________
     
< B O D Y >
___________________
  <PAGE N>

And I would like to have

[Logo]
_________________
< B O D Y>

_________________
   <Page N>

How can this be  made?
