Die von dieser Klasse abgeleiteten Klassen dienen der Bereitstellung von
Defaults von SfxPoolItems und halten konkrete (konstante) Instanzen, die
dann von mehreren Stellen (i.d.R. eines Dokuments) referenziert werden
k"onnen.
Dadurch ist jeder Wert nur einmalig gespeichert, was zu wenig Konstruktor
und Destruktor-Aufrufen f"ahrt, Vergleiche zwischen Items eines Dokuments
beschleunigt und ein einfaches Laden und Speichern von Attributen
bereitstellt.
