There are no such contingencies in XSL-FO for "do empty lines exist?".

By thinking about backgrounds.

No.

All I can think of is the following two steps:

  (1) - create a background illustrating the strike-out region of the page 
for the full size of body region of the last page (in my example below I'm 
just using a silver background colour ... you would probably want to use a 
hash line graphic of some kind)

  (2) - wrap all of the flow in a block whose background is white

Then as the formatter has flow, the region-wide surrounding block with the 
white background obscures the body-region's background ... but this stops 
when the flow stops and the remainder of the page reveal the background 
which will be your hashed line example.

If you are using break-before="page" in your flow then you can only use the 
background image in a conditional page master tested for the last page of 
the page sequence.  If your entire document is simple flow, then it can be 
the background image for every page.

The example below works with both Antenna House and RenderX.

I hope this helps.
