Base Info ServerType

RedundancySupport indicates what redundancy is supported by the Server. Its values are defined in 12.5. It shall be set to NONE for all instances of the ServerRedundancyType using the ObjectType directly (no subtype).

The RedundantServerArray contains an array of available Servers in the Redundant Set; including their service levels (see 12.7). This array may change during a Session; the order of the array elements shall always be the same order as the array elements of the ServerUriArray Variable.
