First of all, sorry about replying above, and not inline .. Nabble isn't really making this easy (or I just haven't figured it out).
Thanks for the extensive reply, much appreciated. It definitely clears up a couple of things for me (and hopefully others). I'll have a look at the cmyk functions, see if I can get something to work. As for the help, *sigh*. I'd do so in a heartbeat, but the truth is I'm simply preparing a study for this project, and I won't actually be the one implementing it. And as can be expected, my next project has nothing to do with XSL-FO, so my chances of contributing something back are very limited. Plus, like you already said, the barrier to enter is quite high. In order to write a decent manual, one is assumed to be at least familiar with that particular field and its corresponding FOP implementation - which I am not. The only thing I have added is an overflow exception in the layout managers when an overflow is detected (rather than printing a warning) since I needed that functionality. It was also raised and proposed on this mailing list but never actually entered in the bug tracker afaict.
