Method parameters are the same as the factory method {@link ItsNatComponentManager#createItsNatComponent(Node,String,NameValue[])}

@param node the node to associate the new component. @param compType the component type, may be null. @param artifacts declared artifacts, may be null. @param compMgr the component manager used to create the component. @return the new component, if null the framework will use the next user defined factory if any or the default factory.
