That's how I read http://wiki.openstreetmap.org/index.php/Relations/ Multipolygon. And tagging multipolygons as in my proposal (i.e., tag the hole as a separate area) didn't seem to work well with either mapnik or osmarender. From what I remember of reading the code, both renderers skip areas with role=inner when rendering. >> In particular, with the proposed >> relation, it's not necessary to create duplicate ways (clockwise and >> anti-clockwise) for holes with properties. > > Who said this was necessary today? > The wiki. And I've seen other people tag like that. I'll update the wiki later if nobody objects, and see what I can do about the renderers. Thanks!
