10.2.19 CMID maintenance
The CM manufacturer is in complete control of allocating CMID values to his manufactured CM devices and there is no service in place to ensure uniqueness of this data element.
CM制造商完全控制将CMID值分配给其制造的CM设备，并且没有适当的服务来确保该数据元素的唯一性。
Once a particular CM is registered in an STS system (typically with a KMC service provider),then the CMID is simply recorded for reference purposes and no further maintenance service on this data element is required.
一旦在STS系统中注册了特定的CM（通常是与KMC服务提供商），则只需记录CMID以供参考，不需要对该数据元素进行进一步的维护服务。
