考虑以下代码：
OWLClass clsA = factory.getOWLClass("cls_A", pm);
OWLAxiom axiom = factory.getOWLDeclarationAxiom(clsA);
manager.addAxiom(ontology, axiom);
OWLClass clsB = factory.getOWLClass("cls_B", pm);
axiom = factory.getOWLDeclarationAxiom(clsB);
manager.addAxiom(ontology, axiom);
OWLObjectProperty propA = factory.getOWLObjectProperty("prop", pm);
axiom = factory.getOWLDeclarationAxiom(propA);
manager.addAxiom(ontology, axiom);
OWLDataProperty propB = factory.getOWLDataProperty("prop", pm);
axiom = factory.getOWLDeclarationAxiom(propB);
manager.addAxiom(ontology, axiom);
axiom = factory.getOWLObjectPropertyDomainAxiom(propA, clsA);
manager.addAxiom(ontology, axiom);
axiom = factory.getOWLDataPropertyDomainAxiom(propB, clsB);
manager.addAxiom(ontology, axiom);
此代码创建具有2个域类的OP和不具有域类的DP。如果存在具有相同名称的对象属性，如何为数据属性创建域属性？是bug吗？
