 *
 *                MTRAttributePathKey : MTRAttributePath object. Included for attribute value.
 *                MTRCommandPathKey : MTRCommandPath object. Included for command response.
 *                MTREventPathKey : MTREventPath object. Included for event value.
 *                MTRErrorKey : NSError object. Included to indicate an error.
 *                MTRDataKey: Data-value NSDictionary object.
 *                              Included when there is data and when there is no error.

 *                MTREventNumberKey : NSNumber-wrapped uint64_t value. Monotonically increasing, and consecutive event reports
 *                                    should have consecutive numbers unless device reboots, or if events are lost.

 *                                           Only present when MTREventTimeTypeKey is MTREventTimeTypeTimestampDate.

 *                Only one of MTREventTimestampDateKey and MTREventSystemUpTimeKey will be present, depending on the value for
 *                MTREventTimeTypeKey.
 *
 *                A data-value is an NSDictionary object with the following key values:

 *                          MTRStructureValueType: structure-value NSArray object.
 *                                                   See below for the definition of structure-value.
 *                          MTRArrayValueType: Array-value NSArray object. See below for the definition of array-value.
