Gestion des pieds de documents en mode XML/3/en

Principle

The idea is to integrate the document footer into a group or into text boxes. Indeed, the objects containing the document footer must be either text areas (text objects) or groups, because they must be processed by the program after the execution of the group potentially generating a page break. These objects will be conditioned on "not triggering" a page break on the page. Concretely, these objects will only be displayed if the current page does not generate a page break, which means that they will only appear on the last page of the document.
