------ The above snippet is part of a pdf/a created by use of iText. They obviously follow those recommendations closely. Indeed, the validator service I've mentioned returns with a report stating the testfile is PDF/A-1b compliant. Adding this to Apache FOP - either by default or configurable - would be welcome. I can imagine it's not high on the demand list though. Maybe I should start a petition ;-) Wim Jeremias Maerki-2 wrote: > > Thank you for the link, Wim!
