I'm still not satisfied with type=multipolygon:

http://wiki.openstreetmap.org/wiki/Multipolygon#Detailed_tagging

specifically:

* The relation has tags:
  Use the relation tagging. Ignore anything on the ways.

However, this is not what should happen for a lake group where each lake
name is independent (ie, the group is just a topological feature). And,
as I said before, unnamed lakes should not inherit the name of the group.

After re-reading the whole thread, I tend to agree with fly more, as a
boundary type seem to be much more appropriate:

type=boundary
boundary=topologic
natural=water
name=lake group name

the boundary relation has the advantage of not requiring a fake polygon
(as opposed to place=locality).

I have two examples of type=multipolygon which I introduced:

http://www.openstreetmap.org/browse/relation/3126464
http://www.openstreetmap.org/browse/relation/3126459

whole type=multipolygon relation simply broke the rendering (but
renderers here seem to be compliant).
