text: According to the wiki, natural=volcano + volcano:status=extinct is the way to map extinct volcanos. It also doesn't make sense to me to assign a volcano:status tag to a peak without a volcano tag.
  
  There is the question whether every extinct volcano should be mapped as such. The English wiki says that it should be verifiable on ground, that is, there should be a crater or lava plugs. The Bausenberg actually has a beautiful horseshoe-shaped crater, and one can still tell in which direction lava flowed (only 200.000 years ago). If any extinct volcano should be mapped as one, it ought to be this one.
