    Hi All,

    I am trying to implement event based solution across various entities inside our architecture. Some of these entities supports TMF622 and some TMF641.

    When i look at event published via TMF622, i can see a field called @type and eventType. But in all examples of events within TMF622, the value is same in both the fields. One Example is below. As you can see both eventType and @type has value of ProductOrderErrorMessageEvent
