The time to live for the current resource lock.
Before a call to the LockResource method, LockTimeout may be set to a specific amount of time needed for the locked operation to take place. The timeout is used to determine how long the lock may exist before the server automatically unlocks the resource URI. If Timeout of 0 is specified, the server will use a default timeout. After a successful LockResource operation, the control will set the LockTimeout property to the correct value returned in the server's response.
