Current Behavior

Are there any mechanisms in the framework that allow handling pre-defined nodes, such as instances of custom object types in the model file (.xml)?

I have pre-defined instances in the .xml of a custom object type. In my custom node manager, I have hard-coded definitions and instances such that:

internal class MyNodeManager : CustomNodeManager2
    {
        private MyServerConfiguration mConfiguration;
        private static CustomTypeState1 mCustomObj1;
        private static CustomTypeState2 mCustomObj2;
        ...

public override void CreateAddressSpace(IDictionary<NodeId, IList<IReference>> externalReferences)
{
            lock (Lock)
            {
                LoadPredefinedNodes(SystemContext, externalReferences);

                BaseObjectState passiveNode = (BaseObjectState)FindPredefinedNode(new NodeId(yourorganisation.org.Planta.Objects.Object1, base.NamespaceIndexes[0]), typeof(BaseObjectState));
                BaseObjectState passiveNode2 = (BaseObjectState)FindPredefinedNode(new NodeId(yourorganisation.org.Planta.Objects.Object2, base.NamespaceIndexes[0]), typeof(BaseObjectState));
               ...
                mCustomObj1= new CustomTypeState1(null);
                mCustomObj1.Create(SystemContext, passiveNode);
                ...
                mCustomObj2 = new CustomTypeState2(null);
                mCustomObj2.Create(SystemContext, passiveNode2);
                ...
                AddPredefinedNode(SystemContext, mCustomObj1);
                AddPredefinedNode(SystemContext, mCustomObj2);
                ....
            }
}

For each node, I need to address it manually and manage every object ID, object type, and namespace and explicit instance. Is there any way to generalize this instantiation for any application? (Suppose there are hundreds of nodes and types in my application).
