Hinweise:
- Wenn ein Artikel einen Sprachparameter nutzt, den diese derzeit noch nicht unterstützt, so sollte der benötigte Sprachparameter im SWITCH-Konstrukt dieser Vorlage ergänzt werden. Zur leichteren Pflege sollten dabei die Sprachcodes in alphabetischer Reihenfolge eingepflegt werden.
- Bei Zusatztext ohne Link ist als Defaultwert " – Quellen und Volltexte" eingestellt. Abschalten mit "X".
