How do you want to do that automatically? It's easy for a human to see that, but very complicated to convert this into an working algorithm. >> To make it a bit more useful, I will an an check, which tests for unclosed >> ways in case of "natural=".

It's no "requirement", but an validation warning. And like all the others, it will be able to turn it off :-) Ciao -- http://www.dstoecker.eu/ (PGP key available) _______________________________________________ josm-dev mailing list josm-dev@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/josm-dev
