>     d1.close();
>     // everything seems fine with the resulting PDF
>     // load and save with protection
>         PDDocument d2 = PDDocument.load(new File("Quelldatei.pdf"));
>     AccessPermission ap = new AccessPermission();
>     ap.setCanAssembleDocument(false);
>     ap.setCanModify(false);
>     d2.protect(new StandardProtectionPolicy("foobar","",ap));
>     d2.save(new File("Zieldatei-mit-Schutz.pdf"));
