page numbering in fo/pdf output (FOP 0.93)

Hello everybody,

 

I’ve noticed that you can change page numbering
in a PDF in the following way:

 

In out PDF generated with FOP (from docbook of
course) the page number displayer in adobe reader looks like this:

 

1 of 100

 

for page 1. Even though page 1 is numbered I (roman)

due to this in our document the first page numbered Arabic
is

 

20 of 100

 

Though the page number _on_ the page is 1.

 

But you can make it look like this:

 

II (2 of 100)

 

And

 

1 (20 if 100)

 

Is this possible in docbook/fop? 

 

Thanks,

            Hinrich
