[OSM-talk] how to tag an island?

[Frédéric Bonifas]

Hi,

I a mapping Lyon and I have a problem of tagging :
There is a park (which I tagged as leisure=park), a lake inside this
park (which I tagged as natural=water) and 3 islands into this lake.
I tried to tag the islands as island=yes and waterway=riverbank but
the render is not good with osmarender (park is displayed in blue, as
water).
What are the good tags for this situation, so that it can be rendered
properly with mapnik and osmarender ?

Thanks in advance.

Fred
