[xsl] How do I line up fo:block's side by side using coordinates ?

[asbjornt <a.r.thorsen@xxxxxxxxxxx>]

I have a form with tables, check boxes and text areas that is preprinted.
I want to use xsl-fo and fop to make a pdf which matches this form. So
when I print out my pdf file at some printer, I hope to match the
preprinted document. I need the fo:block's to be lined up side by side
(hopefully without using tables) using coordinates and width to place the
blocks' at the A4 sheet. How do I line up the fo:blocks like this ?
