9.6.5.6 Task Failure
2010-08-20T11:29:00+02:00 - Before the task expires, 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.
The request is essentially the same as the one shown in Listing 22 2010-08-20T11:29:01+02:00 – The service sends a response with information about the
current status of the task, indicating that the reservation failed at 2010-08- 20T11:28:30+02:00.

9.6.5.7 Updating a Scheduled Task
Assuming that the task is now in execution the client can update it. 2010-08-20T12:40:00+02:00 – The client sends an Update request to the service,
requesting that the camera be moved 10 degrees left. The latest response time is set to 2010-08-20T12:41:00+02:00.

Note: the tasking parameters available for update are a subset of the parameters described in the DescribeTaskingResponse - all parameters that have attribute updatable=false are
not used in an update request. The description of the tasking parameter relevant for an Update request is shown in the following listing.
