由函数afStatus_t AF_DataRequest( afAddrType_t *dstAddr, endPointDesc_t *srcEP,
uint16 cID, uint16 len, uint8 *buf, uint8 *transID,
uint8 options, uint8 radius )的定义可知，它只指定了网络信息接收方的ClusterID并没有具体指定发送方从哪个ClusterID发送出去，既然如此的话
typedef struct
{
uint8 endPoint;
uint8 *task_id; // Pointer to location of the Application task ID.
SimpleDescriptionFormat_t *simpleDesc;
afNetworkLatencyReq_t latencyReq;
} endPointDesc_t;中
typedef struct
{
uint8 EndPoint;
uint16 AppProfId;
uint16 AppDeviceId;
uint8 AppDevVer:4;
uint8 Reserved:4; // AF_V1_SUPPORT uses for AppFlags:4.
uint8 AppNumInClusters;
cId_t *pAppInClusterList;
uint8 AppNumOutClusters;
cId_t *pAppOutClusterList;
} SimpleDescriptionFormat_t;的pAppOutClusterList还有什么意义了？
