I am just trying to hack the XSL used for creating PDF files out of docbook-slides-xml ... but tend to get lost in all the magic they are doing. So I thought looking at your XSL will help me jumpstart into XSL fundaes ...
An honest confession here... I get lost into my own XSL stylesheets too. But I'll be glad to help you for pinning your XSL beast down.
