Re:  Getting a block to end on the last page
There are two separate things that can determine how many pages there
will be, which is why it matters. On a given report, there's a list of
charges that need to be displayed, and a list of items on a shipment
that need to be displayed, and a list of notes about the items. Any of
those three, the charges, the items or the notes could be the piece
that extends the longest, and determines how many pages there are. If
it's the charges that are longest, great. Our work is done. We just
start the charges on the first page, and they end on the last.
However, if the charges are NOT the longest piece, as in the example I
provided, then we need to start the charges on a different page. The
second, in the example. Now, I can figure out how many pages each
portion will take up, and determine from that what page to start the
charges on, but I was hoping there might be a more elegant way to do
it in XSL-FO.

Does that make sense?
