vertical line between margin and text

Hello,

I have following problem: I'd like to insert a vertical line between
text body and left margin. On the left margin, there will be an image
in header and a short text on footer. The actual problem for me is how
to add that vertical line (from the top to the bottom of page). I use
Norman's XSL stylesheets for FO.

Could anyone help me?

Thanks in advance.
