If I would print a map for a customer, I would follow his assumptions most probably, but I disagree for the "default" style(s) on the osm.org website, as these in fact are driving factors to how people tag. If people tag multipolygons right (tm), this should be honoured by a correct display on the map. If it's wrong they should see that there's an error, therefore IMHO the default stylesheet MUST NOT gracefully forgive these errors as a map more dedicated to end users would probably do.
Following these assumptions on the main map which is often used to check the correctness of the own edits means to hide errors and to tell mappers the wrong thing: you have done all right - where that's not the case. regards Peter _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
