> FOP currently always creates a file ID in the PDF trailer even though it's optional.
It is required mostly be PDF/A and PDF/X. It may make sense to disable the generation via
a configuration item. We probably shouldn't disable it by default because some people may
rely on it by now.
> Second, the metadata date is always set to the current date even if it is given in an
XMP packet. That also prohibits binary equality.
> Adding this would allow Forrest to produce the same PDFs from run to run so they don't
cause SVN diffs all the time.
