This is probably the hardest bit. I'm not familiar with the format of a
DJDE file, but if it's proprietary you'll have to buy the format
description from Rank Xerox. There appear to be a number of conversion
programs on the market (Google for "djde file format") which might be
a faster way to get XML.

You can generate a skeleton file of XSLT templates (rules for each 
element type) from the XML document (there are several little XSLT 
routines you can download to do this), but you'll still have to write 
the code for what you want each template to *do*, so generating an XSLT
file is not usually much more than a 10-minute convenience time-saver.

These usually go together. There are lots of commercial products to do 
this. AFAIK, fop is the only completely free one. You don't use XSLT:
the language for generating FO is XSL.

If you know LaTeX, however, you can use XSLT to generate LaTeX source
code and use that to create your PDF. LaTeX is free (www.tug.org) but
it's an additional learning curve unless you're already a user.
