Hi Ticker, my understanding is that a valid multipolygon doesn't contain other relations. Where did you find them?

It doesn't handle it in two ways: 1/ During the reading of relations, if the relation references another relation that hasn't been read yet, it is added to a deferred list and when the second one is defined, the element is added to the first. However, for multiPolygons, the processing is performed as each one is read. 2/ In MultiPolygonRelation, an inner or outer that is a multipolygon relation is not handled; instead the warning "Non way member in role" is generated. The above warning is also generated for members with role "subarea"; these should be ignored without warning. I've attached a patch to generated warnings in case 1/ and to improve the warnings in case 2/. In the longer term it should be implemented. I was surprised how few inner/outer as multipolygon there are in OSM/British Isles. Maybe it isn't well supported by the various map generating software packages and so people don't use it.
