But the problem is in how to handle tagging in this case. The existing
wiki "rules" describe only the tagging of top outer rings, but they
don't mention how to handle various cases/combinations of tagging holes
within holes.
The area of the "hole within the hole" does not require special tagging,
as it is covered by the multipolygon itself. If you have a forest with a
hole in a hole, then that hole in a hole is forest as well.
If you are, on the other hand, thinking of a "lake in the middle of a
meadow in the middle of a forest" situation, then this is not "hole in a
hole" - the forest has one hole which is the meadow, and the meadow has
one hole which is the lake. You would have three ways:
F - tagged as forest
M - tagged as meadow
L - tagged as lake
and two multipolygons
MP1: outer=F, inner=M
MP2: outer=M, inner=L
You have the option of leaving F and M untagged and attaching the
forest/meadow tags to MP1 and MP2 instead.
