18297	Invalidate natural=water with no other tags	pangoSE	Don-vip	"Hi
I think lakes only tagged with [osmwiki:Tag:natural=water natural=water] is wrong. 
Could we add this to the validator?
In Västernorrland in Sweden alone I found ~1700 lakes missing the [osmwiki:Tag:water=lake water=lake] tag.

(FYI I did this:
natural=water and key!=waterway and key!=water in ""västernorrland"" <- overpass turbo wiz
""natural=water and -water=* and -waterway=* and (type:way or type:relation)"" <- search in josm - I excluded nodes to avoid some incorrectly tagged bays near Sundsvall)"	enhancement	closed	normal	19.11	Core validator		fixed	natural water
