(OPC UA) Creation of instance from an ObjectType is faulty

Requirement concerned:

As a User, I want to create instance objects from an ObjectType within the OPC UA Information Model.

Description:

In the OPC UA Information Model under Information Model->Nodes->Types->ObjectTypes->BaseObjectType, the ObjectType DemoDevice is defined. It has two sub ObjectTypes, Actuator and Sensor, as per the structure Information Model->Nodes->Types->ObjectTypes->BaseObjectType->DemoDevice. However, when creating an instance object from the DemoDevice ObjectType (Information Model->Nodes->Objects->DemoDevice), the instance should not generate the ObjectType defined node und NOT from its subtypes. The current behavior is contrary to this expectation, leading to errors and inconsistencies in the system. Furthermore this is not complaint to the OPC UA Information modelling rule.

Steps to reproduce:

1. Access the OPC UA Information Model at Information Model->Nodes.
2. Attempt to create an instance from the DemoDevice ObjectType at Nodes->Objects.
3. Observe the generation of unnecessary elements, which should not occur as per the model definition.
