The agent will be in a better position to take this decision as it will 
be interfacing between actual card reader and SAP server.

For example, if the agent is connected to an external card reader and 
it has lost connection with the reader. It can ask for an Immediate 
disconnection.
If disconnection was triggered by a user action, it can decide to call 
this API with Graceful as the parameter.

One candidate would be when the MessageSize is changed.
Another one will be with the "SimStatus" property. It makes sense to 
raise his signal after the server sends the STATUS IND response 
successfully.

But, it is a fact that most of the Properties are set by the Agent 
itself. So agent will know that they have changed.
