Yes, but only if these are the only values (for rangeIncludes/domainIncludes).
As soon as there are more than one, the correct mapping would be to use an
owl:unionOf. And that is hard to create from SPARQL as it requires building an
rdf:List. Alternatively, the same effect as domainIncludes can be achieved by
defining a sh:property (or owl:Restriction).
