 *
 * HEADERSHARE - Content of header is equal on left and right hand pages.
 * FOOTERSHARE - Content of footer is equal on left and right hand pages.
 *
 * The values are masked out in the respective getter and setter methods.
 * Access to complete m_eUse including the information on header and footer
 * via ReadUseOn(), WriteUseOn() (for Filter and CopyCTor)!
 *
 * The Frmformats for header/footer are adjusted by the UI according to
 * the attributes for header and footer at master (height, margin, back-
 * ground ...)
 * Header/footer for left hand pages are copied or mirrored (Chg at
 * document).
 * The respective attribute for content is cared for automatically on Chg at
 * document (contents are created or removed according to SHARE-information).
