I wonder whether this class works properly when multilingual mode is
disabled. Particularly for the `rdfs:label "Berlin"@de, "Berlin"@en` case where
one of them is removed, does the index still understand that one "Berlin" value
should be retained? I suggest that what is currently the multilingual mode
should be the only possible mode.
