"rdf:" not found when sending a federated query to Fuseki

[MaillPierre]

Tested with Fuseki 4.6.1.

When sending a federated query that contains the "a", to remplace "rdf:type" to a fuseki service through corese, the query sent by corese to the service replace the "a" by "rdf:type" but do not include the namespace "rdf:"

For example, for the following query sent to corese:

PREFIX prov: <http://www.w3.org/ns/prov#>
PREFIX earl: <http://www.w3.org/ns/earl#>
PREFIX kgi: <http://ns.inria.fr/kg/index#>
PREFIX void: <http://rdfs.org/ns/void#>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
INSERT {
    ?datasetDescription  void:classPartition ?classPartition .
    ?classPartition void:class ?c .
}
WHERE {
    SERVICE <http://localhost:3030/DekalogDebugEmpty/sparql> {
        { ?s a ?c . }
    }
    BIND(Iri(CONCAT(str(kgi:), MD5(str(<http://localhost:3030/DekalogDebugEmpty/sparql>)), "Dataset")) AS ?datasetDescription)
    BIND(Iri(CONCAT(str(kgi:), MD5(CONCAT(str(<http://localhost:3030/DekalogDebugEmpty/sparql>), str(?c))), "Partition")) AS ?classPartition)
}

The following query is received by fuseki:

prefix kgi: <http://ns.inria.fr/kg/index#> 
prefix prov: <http://www.w3.org/ns/prov#> 
prefix void: <http://rdfs.org/ns/void#> 
prefix earl: <http://www.w3.org/ns/earl#> 
select *  where {   {?s rdf:type ?c .} }

The rdf namespace has disappeared and the server returns a 400 error.
