Also, to refine the tagging schema:
- for the new RP6105
- In CNER SHP the "ordreArc=11" is tagged as "etat=-1" that should be tagged as "proposed" in OSM
- But the way "highway=track" exists in OSM

Do you have an idea on how should I tag it to keep the way as "highway=track" and add the "proposed" official reference "ref=RP6105" ?

sorry if I'm too picky ;-)
