consider using schema:domainIncludes, rangeIncludes

[VladimirAlexiev]

In relation to OP-TED/model2owl#136:

In addition to rdfs:domain,range consider also using schema:domainIncludes, rangeIncludes.
Unlike the rdfs props, the schema props are polymorphic, i.e. can take multiple values.

That's what we did in GS1 EPCIS, see gs1/EPCIS#222 and this example https://github.com/gs1/EPCIS/blob/master/Ontology/EPCIS.ttl#L201 that illustrates well the simplicity of schema:

epcis:action  a           owl:DatatypeProperty , rdf:Property ;
        rdfs:domain       [a owl:Class ;
                           owl:unionOf (epcis:ObjectEvent epcis:AggregationEvent epcis:AssociationEvent epcis:TransactionEvent)] ;
        schema:domainIncludes epcis:ObjectEvent, epcis:AggregationEvent, epcis:AssociationEvent, epcis:TransactionEvent;
        rdfs:range        xsd:string ;
        schema:rangeIncludes xsd:string ;
