Hi,
This is an old problem that I looked into some time ago.
I use my ant4docbook project daily to generate pdfs, from docbook,
markdown and docbook xsl1.xx.
Surely there are some interesting things to take in there.
The next step is to use xsltng + an html to pdf converter (chromium cef pdf?).
Regards,
Benjamin
