What about the 'Designation' tag?
The key:designation tag is used to add information about legal use/protection of a way or area. Protected Planet also makes use of the the phrase "designated" (the protection title, as in the local countries legislation) and "designation type" (national or international). Developing on this you could use the tag designation_category=* or the existing protect_class (if it fits in an IUCN category). --RobJN 18:29, 17 November 2012 (UTC)
