I've been taking all three objects and merging them. So the inner is
natural=wood, with name.

Seems to be rendering ok. Childs and Osawa are examples.

You are right :-(
Two solutions are possible for the next release...
- Convert natural=land area into point feature - the easy solution to
always keep the name available;
- Associate the name to the inner component - If it renders properly.
The second one is much more complex (from my side). Can someone try it
and send me the conclusion?

I notice for islands with names the name tag is on the natural=land.

I wrote "natural=land area features are a duplicate of natural=water inner

there."
I understand that natural=land has priority in the rendering. Rendering will then "move"
any overlapping features "under" the natural=land feature. It means you are better remove
natural=land area before importing.
The standard case for an island is
- an inner component of a relation type=multipolygon : natural=water
- a polygon : natural=land
- a polygon : natural=wood
Remove the polygon natural=land and the polygon natural=wood will render
properly in the hole created by the inner component of the natural=water
multipolygon.

Subject: [Talk-ca] Sinking islands...
I was importing data in the Georgian Bay area and I noticed
something. If an island is natural=land it renders in mapnik as white,
regardless of the outer multipolygon. if you have natrual=wood or
possibly others, it sinks if it's not role=inner.
This is at least what I've observed so far. It's rather hard to figure
out when the mapnik tiles get cached and don't refresh in a timely fashion. :-)
