Now there are several options: the task automatically expires at 2010-08- 20T11:30:00+02:00, the client confirms, updates or cancels the task beforehand or the
task fails for some reason. The option that the reservation was updated is not considere here.

2010-08-20T12:00:00+02:00 – The client sends a GetStatus request to the service. The since parameter, although supported by the service, is not used in the request. Thus the
current status of the task is requested.
