Thanks for the arguments, I will put the source tag into the changeset.
@Serge: I don't think it would be a good idea to remove the current source
tags. Ok if it would be saved in the history but I think it must be easely
visible because of the agreement with the French gouvernement. And yes the
value is a bit long but I think the update time ("Mise à jour : 2010") is
mandatory too..
