Okay, didn't know that.
But if I wish to just add these data as info fields? Here is a dump taken using
pdftk dump_data:

I know that it's possible to add info fields using
pdftk update_info. Maybe they won't be supported, but at least I'll know that the additional metadata is built into the file.
Is there a way to automatically extract the XML from the OPF file and add it to the PDF using
pdftk update_info?
BTW, this is an awesome app!
