/* This demo shows you how to do batch signing through the Swisscom All-in Signing Service.
 *
 * It uses the signature standard "PAdES-baseline" (default) and a timestamp signature. The revocation information of
 * both are added to the Document Security Store (DSS) afterwards to have LTV enabled (PAdES Signature
 * Level: B-LT).
