One Mapnik render later, we have some solid data:

Multipolygons with untagged inner elements (per wiki): Don't render on Mapnik
Multipolygons with inner elements tagged as the outer ones: Do render on Mapnik

At this point, we _could_ define the current behaviour as a standard,
update the wiki and change whatever data isn't compliant.

*or* we can see if the Mapnik brains are willing/able to support
multipolygons according to the current wiki instructions.

I don't really mind which, since certainty is all we really need here.

Opinions?
