I have jfor working with my docbook FO files by adding support for em 
units and proportional-column-widths. Only works with articles, not 
books, as the latter references the "body-start()" function. 
Appended/attached are the patched files and one new file. I'll put a 
copy of the jar on my web site if anyone wants to try it out.
