The second bullit describes this requirement.

Basically we are dealing with an "old" and a "new" tagging scheme. And the only
way to differentiate is looking at the tags of the relation.

It would have been nicer, if the "new" implementation would use
type=advanced_multipolygon for distinction. But sadly this is not the way, the
OSM world is working.
