Per discussion with HT a couple of weeks ago, added a background watermark image to articles and reviews which have not yet been published. Easy for the XHTML, but a little trickier for the PDF; took a while to figure out where to add it (fo:region-body in all fo:simple-page-masters), and how exactly to set it up (using custom rx:background-content-width attribute to specify the width in inches, since it's an SVG image).
