 * UI dreht auschliesslich am Master! aLeft wird beim Chg am Dokument

 *
 * Damit es die Filter etwas einfacher haben werden weitere Werte im

 *
 * HEADERSHARE - Headerinhalt auf beiden Seiten gleich
 * FOOTERSHARE - Footerinhalt auf beiden Seiten gleich
 *
 * Die Werte werden bei den entsprechenden Get-/Set-Methden ausmaskiert.
 * Zugriff auf das volle eUse inclusive der Header-Footer information
 * per ReadUseOn(), WriteUseOn() (fuer Filter und CopyCTor)!
 *
 * Die FrmFormate fuer Header/Footer werden anhand der Attribute fuer
 * Header/Footer vom UI am Master eingestellt (Hoehe, Raender, Hintergrund...);
 * Header/Footer fuer die Linke Seite werden entsprechen kopiert bzw.
 * gespielt (Chg am Dokument).
 * Das jew. Attribut fuer den Inhalt wird automatisch beim Chg am
