A beast of many things...
I've had need (or nerd, rather) to look at the specs at some point, and there's so many bewildering things in there... base95 (because why waste characters?), a freaking filesystem, because that's really what PDF is... I want to say there's special support for barcode-ish things in there, too, but I've not found it looking at the PDF1.7 ISO document.
I can see how they were convinced it would be a great step towards low-paper office workflows, if you go all in, all the way.
