}

The entry is a type of change that needs to be applied. It contains two data fields. While the fields are built into the model; their usage is determined by the entry_type.

For normal entries, the data field should contain the data change that should be applied. The context field can be used for any contextual data that might be relevant to the application of the data.

For configuration changes, the data will contain the ConfChange message and the context will provide anything needed to assist the configuration change. The context is for the user to set and use in this case.
