Apart from a working keep-with-prev this would need
a block layout algorithm able to compute a variable
amount of space depending on constraints. None of this
is currently implemented, and even if it were, the
result is not quite predictable.
A more robust way would be to use a two row table of
100% page height and display-align="after" on the
second row, but this isn't implemented either.

You can try a somewhat ugly footnote hack:
       <fo:block break-before="page">top </fo:block>
       <fo:block>
         <fo:footnote><fo:inline></fo:inline>
           <fo:footnote-body>
             <fo:block>bottom </fo:block>
           </fo:footnote-body>
         </fo:footnote>
       </fo:block>

Hi

Thank you both for your help.

I have used Matt's suggestion re table and a one-pixel-wide,
half-a-page-tall clear image.

It works fine.

Thanks again

Peter

You might try making a table with two columns and two rows. Make the
first (or last) column one pixel-wide and have each row of that column
contain a one-pixel-wide, half-a-page-tall clear image. This is an HTML
trick, please let me know if it works on FOP. (I've attached the image,
you'll need to resize it.)
