Hello,I am guessing i cant share a link so below is what one of the sub classes look like.When i create an instance of sequence which satisfies the restriction below i expect jena to infer it being a BusRide but i dont get that.I also made the super class "Sequence" a unionof all the restricted subclasses.When i infer a sample of the output is despite giving an avg_speed that satisifies the restriction.sequence1 is inferred to be in class urn:absolute:VehicleClassification#Sequencesequence1 is inferred to be in class http://www.w3.org/2000/01/rdf-schema#Resourcesequence1 is inferred to be in class http://www.w3.org/2002/07/owl#Thingsequence1 is inferred to be in class -68f948bd:159df30c0e5:-7fe3
