    * Server Id
    * A Server ID must uniquely identify a server to an IMR. 
    * This specification only requires unique identification using a string of 
    * some kind. We do not intend to make more specific requirements for the 
    * structure of a server ID. 
    * The server ID may be specified by an ORB_init argument of the form 
    * -ORBServerId 
    * The value assigned to this property is a string. All templates created in 
    * this ORB will return this server ID in the server_id attribute. 
    * It is required that all ORBs in the same server share the same server ID. 
    * Specific environments may choose to implement -ORBServerId in ways that 
    * automatically enforce this requirement... etc...
    * 
    * A ServerId, in the context of LWFT identifies a ServerGroup. 
    * All servers with a common ServerId are replicas of each other and members of 
    * the same ServerGroup.
