@Hans:
I'll look into it. Give me some days to read the documentation (not that
much anyway) and to play around with it.
All the "new" features are already implemented as building blocks for
the PDF/X variants, so I guess it's mostly just adding some new table
entries ('b|u' variants). Attachments seem to need several extra PDF
entries. Will report back to you and Luigi.
@Luigi: mh, that really looks like a lot of fun

@Pablo, Rik:
We can put you in cc if you volunteer for testing. Just say aye :D
