On top of tagging different layers for a park and its lake not being "clearer and more accurate", it really is a renderer decision wether to render a park on top of a lake or vice-versa. For example if your rendering of "leisure=park" is a very transparent green area, then you do want to render it on top of lakes and all other features. So please do not use the layer tag for that purpose. _______________________________________________ talk mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk
