I did find a version of spatialite that supported build area after I had written the multipolygon code, but I've decided to keep the code in osm2spatialite because it does a much better job of generating valid multipolygons that BuildArea can (because BuildArea doesn't have a concept of the inner and outer roles).
Can you elaborate on how having "inner" and "outer" roles helps one in building a valid geometry?
Reason I'm asking is that in all the code where *I* generate geometries from multipolygon relations, I explicitly ignore the role because using the role would actually lead to more, not less, invalid multipolygons.
