```I can not use a query like this to delete some triples :
DELETE { ?s ?p ?o } WHERE { ?s ?p ?o . ?s ?o . FILTER ( langMatches(lang(?o), 'FR') )}

This has no effect but the following delete all the triples with a
refs:label predicate ?
DELETE { ?s ?o } WHERE { ?
s ?o . FILTER
( langMatches(lang(?o), 'FR') )}```
