        This will allow to decrease a lot the duplication of code among the generator...

        At least in ods, chart are special  because we need to attach them to the main document's 
spreadsheet. 
This seems possible in flat ods document but I do not success to do that in classic ods document =>
I end creating automatically a true embedded chart in "Object */*"….

        Yes, I was also thinking of integrated documents where we may need to create some embedded 
graphic/spreadsheet/...

        Ok.
