For example,
http://www.openstreetmap.org/?lat=-34.03275&lon=151.13694&zoom=17&layers=M
Along the edge of the bay/water there is
land--> | <--trees in water--> | <-- water
A B C
In the changeset http://www.openstreetmap.org/browse/changeset/6723657
I moved the edge of the water (which did cover both B and C) in
towards the center of the bay, and made section B marsh. But I'm not
sure if that was the right thing to do. Maybe it would be better if
the natural=bay/water area included both B and C, and the boundary for
B just laid on top of the B/C area. But since we use a proper
mulitpolygon for doughnut geometries, just dumping B on top wouldn't
look so nice....
What if B was tagged as marsh, C as water, and then add B and C to a
multipolygon tagged as the bay? Or is how its mapped currently how it
should be? Any thoughts?
