A fixme will be added to the point.\n\nNote that a soft deletion is _only_ possible if these tags are provided by the theme creator, as they'll be different for every theme\n\n#### No-delete options\n\nIn some cases, the contributor might want to delete something for the wrong reason (e.g. someone who wants to have a path removed \"because the path is on their private property\").\nHowever, the path exists in reality and should thus be on OSM - otherwise the next contributor will pass by and notice \"hey, there is a path missing here! Let me redraw it in OSM!)\n\nThe correct approach is to retag the feature in such a way that it is semantically correct *and* that it doesn't show up on the theme anymore.\nA no-delete option is offered as 'reason to delete it', but secretly retags.",
