We can certainly get rid of everything that's specific to FOP.

We do need to retain
  {multiple,single}_cell_document::validate_with_xsd_schema()
  {multiple,single}_cell_document::cell_sorter()
and I suspect that means we must also keep 'ledger_xsl.?pp'...

...but maybe I've guessed incorrectly and 'ledger_xsl.?pp' can
be eliminated.
