+Issue #1 (Bug oder Feature ?)
Bei der Signatur eines Dokuments, dem zuvor eine leere letzte Seite hinzugefügt wurde, befindet
sich die Signaturmarke am Beginn dieser letzten leeren Seite selbst wenn auf der vorletzten Seite
noch genügend Platz zu Verfügung stehen würde.
+Issue #2
+Bei Aktivieren eines Minimallayout-Profils wurde bei der der Prüfung beliebiger Dokumente ein
+Problem festgestellt:
+
+"java.lang.RuntimeException: There is no SIG_DATE in the list of found_keys. This must not happen."
+
+Bei der Definition eines Minimallayouts können bisher verpflichtende Einträge für die Signaturmarke
+weggelassen werden (entsprechende Einträge SIG_XXX-cv in den Tabellen sowie entsprechende Keys
+sig_obj.PROFIL.key.SIG_XXX=XXX).
+In der eingecheckten Konfiguration (work-Verzeichnis) existieren zwei solche Minimallayouts.
+
+Da mit derselben Konfiguration auch Signaturen mit dem Minimallayout durchgeführt werden sollen,
+kann dieses nicht einfach deaktiviert werden (für eine Verifikation binärer Signaturen benötigt man
+keine aktiven Profile).
+
+Ein Hinzufügen der Zeilen:
+
+sig_obj.SIGNATURBLOCK_MINIMAL_DE.key.SIG_VALUE=Signaturwert
+sig_obj.SIGNATURBLOCK_MINIMAL_DE.key.SIG_NAME=Unterzeichner
+sig_obj.SIGNATURBLOCK_MINIMAL_DE.key.SIG_DATE=Datum/Zeit-UTC
+sig_obj.SIGNATURBLOCK_MINIMAL_DE.key.SIG_ISSUER=Aussteller-Zertifikat
+sig_obj.SIGNATURBLOCK_MINIMAL_DE.key.SIG_NUMBER=Serien-Nr.
+sig_obj.SIGNATURBLOCK_MINIMAL_DE.key.SIG_KZ=Methode
+sig_obj.SIGNATURBLOCK_MINIMAL_DE.key.SIG_ID=Parameter
+
+hat das Problem übrigens auch nicht gelöst.
