* Objects means tables, images, text frames and shapes
* Implementation
** MSO uses simple bookmark references as cross-references to objects
** So generate bookmarks in export time if a caption is referenced
** In some cases we also need to split some of the runs
** Implemented all types of cross-references, except the chapter reference
