9.6.5 Scheduling a Task Submit Reserve
2010-08-20T11:10:20+02:00 – The client reviews the alternatives and decides to use the first one with slight alteration of the task start time setting it to 2010-08-
20T12:37:00+02:00. The client then adds some more specific parameters to control the camera. It requests that the camera looks at the location [geodetic latitude 51.902112 deg,
geodetic longitude 8.192728 deg, ellipsoidal height 0 meter] and sets the focal length to 3.5mm.
2010-08-20T11:12:00+02:00 – The client schedules the task. This can be done either via directly submitting a task or by reserving it first and then confirming it a bit later on
which is useful for scenarios where multiple sensors need to be tasked together.
9.6.5.1 Task Submission
2010-08-20T11:12:00+02:00 – The client sends a Submit request to the service. The latest response time is not set for this request, so the client is willing to wait however long
the processing of the response is going to take.

9.6.5.2 Reserving a Task
2010-08-20T11:12:00+02:00 – The client sends a Reserve request to the service. The latest response time is set to 2010-08-20T11:20:00+02:00. The expiration time of the
requested reservation is set to 2010-08-20T11:30:00+02:00.
