In my point of view the multipolygon relation is a much to complicated
construct, which should be disregarded. Everybody you ask, has a
different understanding of its meaning. And as far as I know, there is
no complete implementation of this feature yet. (The Mapnik support is
only partly.)

Since people are using the relation, it would be nice, if mkgmap could
support this. But the better solution is, to discourage people from
using this feature at all :-)
