What would you want to do exactly in the l10n_fr module ?

These kind of indications on the invoice should be added in the invoice report. The invoice report in lp:openobject-addons is in RML, but, as RML is such a pain, most people now use reports designed with other engines such as webkit, aeroo, jasper or pentaho. So I really don't see what you would like to add in l10n_fr. For me, you just have to update the invoice report that you are using on your openerp instance.
