I want to know how to get this right, as my interest is hiking and
many of the parks I frequent have ponds or lakes as part of the park.
There seems to be more feedback than the last place I asked (
http://forum.openstreetmap.org/viewtopic.php?id=6484 ).

IMHO, landuse= and natural= should be orthogonal functions.  Something
can be one or both.  A large area of landuse=park can include within
it a smaller area that is natural=water.  If someone uses the OSM data
to compute the area of the park, it should include the area of the
lake.  One could even imagine lakes that are partly within and partly
outside a park.

Whatever is actually there, the renderer should be able to handle it.
The renderer should color the land part of the park green and the
water part blue.

Best regards,
-Jeff
