Hope is good. ;-) Usually, problems don't just disappear.

"empty cell areas": When a table-cell is broken over two pages, it
generates two so-called reference areas. If the table-row that it
belongs to is broken over two pages but the full content of a table-cell
fit on the first page, FOP still has to create a (empty) reference area
for that table-cell on the second page. What you want is to place an
image in that empty area. My suggestion was to have a facility to
specify content that would be distributed into these empty reference
areas generated by the table-cell. The only tricky thing is to let the
height of that content influence the actual height calculation for the

Disclaimer: If I'm talking about possible solutions that doesn't mean I
offer to implement it.

Vincent is working on the page breaking code of FOP so it can do things
it currently can't and so we can one day format documents of arbitrary

You lost me. Sorry. Sounds adventurous anyway.
