GeneralModelChangeEvents are Events of the GeneralModelChangeEventType. The GeneralModelChangeEventType is a subtype of the BaseModelChangeEventType. It contains information about the Node that was changed and the action that occurred to cause the ModelChangeEvent (e.g. add a Node, delete a Node, etc.). If the affected Node is a Variable or Object, then the TypeDefinitionNode is also present.
To allow Event compression, a GeneralModelChangeEvent contains an array of changes.
