Jeremias Märki sent me some example files for doing PDFs with the help of XSL:FO, Apache FOP (besides some patches to the tal2xslt.xsl template) and XSLTAL. This shows, that XSLTAL is not only useful for doing HTML pages, but for also making PDFs. If you look at the tal template he made, you can see, that this is a fully XSL:FO valid document. You can even transform that with FOP and of course edit it with your preferred XSL:FO editor. But if you throw XSLTAL and this ticket.xml in between, you get nice little tickets with your content. Cool stuff and thanks a lot.
See our Subversion repo at http://svn.bitflux.ch/repos/public/misc/xsltal-fo/ for all the files and a tar archive for all of them.
