> This is caused by the following malformed markup from dbpedia:
> {code}
> dbr:Trento geo:geometry "POINT(11.116666793823 46.066665649414)"^^virtrdf:Geometry ;
> dbp:mayor "Alessandro Andreatta"^^rdf:langString ;
> dbp:imageFlag "Flag of Trento.png"^^rdf:langString .
> {code}
> I propose that, for string literals of datatype "langString" with no language tag, we should simply fall back to type "string".
