    Description

      The model enables to execute following command.

      /subsystem=messaging-activemq/server=default/ha-policy=replication-master:add
      

      It creates ha policy with following configuration.

      /subsystem=messaging-activemq/server=default/ha-policy=replication-master:read-resource 
      {
          "outcome" => "success",
          "result" => {
              "check-for-live-server" => false,
              "cluster-name" => undefined,
              "group-name" => undefined,
              "initial-replication-sync-timeout" => 30000L
          },
          "response-headers" => {"process-state" => "reload-required"}
      

      From the description of cluster-name attribute it is not clear what is the behavior if this attribute is undefined.

      "cluster-name" => {
             "type" => STRING,
             "description" => "Name of the cluster used for replication.",
             "expressions-allowed" => true,
             "nillable" => true,
             "min-length" => 1L,
             "max-length" => 2147483647L,
             "access-type" => "read-write",
             "storage" => "configuration",
             "restart-required" => "all-services"
      },
      

      The ActiveMQ Artemis documentation describes the attribute as follows:

      Name of the cluster configuration to use for replication. This setting is only necessary if you configure multiple cluster connections. If configured then the connector configuration of the cluster configuration with this name will be used when connecting to the cluster to discover if a live server is already running, see `check-for-live-server`. If unset then the default cluster connections configuration is used (the first one configured).
