Beim Parsen von text-basierten Vorlagen (HTML, LaTeX) kann jetzt in der ersten Zeile das Format der Tags bestimmt werden. Dazu wird etwas wie "((set-tag-style))" benutzt. Die Nicht-Leerzeichen links und rechts vom Wort "set-tag-style" bestimmen, wie ein von Lx-Office zu parsendes Tag beginnt und wie es endet.
