If you define advanced multipolygons to allow this then it is no longer ugly but "specified behaviour" ;-) - but as I said, I'm not fond of touching rings either, it was someone else who stuffed that into the Wiki against my advice. > I also would like to see the feature to handle > old style multipolygons removed (inner and outer with the same tags) as > this would provide an incentive to change these polygons to the new tagging > scheme. As map renderers, we have to educate mappers to do the right thing, but also we have to try to make the best maps from the material available. I think that removing support for old-style polygons would be premature. We should also try to get not too far out of touch with Mapnik. The thing I hate most about multipolygons is the idea that certain rings need to be clockwise or counter-clockwise. This pops up every so often and I always say it is rubbish and then people produce some strange example where it really makes a difference ;-) I hope we've now got rid of these cases once and for all.
