Hallo Frank,
Cocoon macht mithilfe von XSL-FO aus XML PDF-Dateien.
http://xml.apache.org/cocoon/index.html
bzw.
direkt das XML-FOP-Project der XML Apache Group
Zitat:
"The goals of the Apache XML FOP Project are to deliver an XSL FO->PDF formatter that is compliant to at least the Basic conformance level described in the 27 March 2000 XSL WD, and that complies with the 11 March 1999 Portable Document Format Specification (Version 1.3) from Adobe Systems."
