9458	detect emergency=permissive as bogus	mkoniecz	team	"http://wiki.openstreetmap.org/wiki/Key:access#Values

""permissive Open to general traffic until such time as the owner revokes the permission which they are legally allowed to do at any time in the future."" (in this)

http://wiki.openstreetmap.org/wiki/Key:access#Land-based_transportation

""emergency=* (category: emergency motor vehicles; e.g., ambulance, fire truck, police car)""

I am not aware about any country where owner may revoke access to emergency vehicles, most likely emergency=permissive makes no sense everywhere and probably it should be replaced by emergency=yes in most situations.
