Boundary is used on ways and relations (and even on nodes..). I don't
have a problem with using boundary ways if the boundaries are a set of
disjoint, simple polygons like in this case. It's a shame that they
are not rendered in default mapnik but that argument can't prevail
over logical classification arguments.
Maybe we should just introduce a new set of boundary= tags for the
various NPS domains:
There are 37 classes in total, most of them with only a few instances.
What do y'all think of that idea?
 Already in use, oddly 182 out of 183 uses are nodes, seems like an
unfinished or ill-advised edit session:
