/**
 * This DE reprents the absolute accuracy of a reported vehicle acceleration value with a  confidence level of 95%. 
 *
 * The value shall be set to:
 * - `1` if the acceleration accuracy is equal to or less than 0,1 m/s2.
 * - `n (n > 1 and n < 100)` if the acceleration accuracy is equal to or less than n × 0,1 m/s2.
 * - `100` if the acceleration accuracy is equal to or less than 10 m/s2.
 * - `101` if the acceleration accuracy is out of range i.e. greater than 10 m/s2.
 * - `102` if the data is unavailable.
 *
 *
 * @note: The fact that an acceleration value is received with confidence set to 'unavailable(102)' can be caused by several reasons, such as:
 * - the sensor cannot deliver the accuracy at the defined confidence level because it is a low-end sensor,
 * - the sensor cannot calculate the accuracy due to lack of variables, or
 * - there has been a vehicle bus (e.g. CAN bus) error.
 *
 * In all 3 cases above, the reported acceleration value may be valid and used by the application.
 * 
 * If an acceleration value is received and its confidence is set to `outOfRange(101)`, it means that the value is not valid and therefore cannot be trusted. Such value is not useful for the application.
