[SHACL] sh:prefixes

[Martynas Jusevičius]

Hi,

Does Jena's SHACL engine support sh:prefixes? Or am I using them wrong?

The following test shape

@prefix skos:   <http://www.w3.org/2004/02/skos/core#> .
@prefix sh:     <http://www.w3.org/ns/shacl#> .

<#ConceptBroaderCycleShape>
    a sh:NodeShape ;
    sh:targetClass skos:Concept ;
    sh:sparql [
        a sh:SPARQLConstraint ;
        sh:message "Concept is broader than itself (directly or indirectly)" ;
        sh:prefixes skos: ;
        sh:select """
            SELECT *
            {
                $this skos:broader+ $this .
            }
            """ ;
    ] .

returns an error:
