GDS that supports AliasNames,provides AliasNames functionality, but the target Nodesreferenced are in other Servers.The AliasNames are aggregated from the Serversthat have registered with the GDS that expose the “Alias" capability (for information on capabilities see OPC 10000-12). Additional examples on aggregating AliasNamescan be found in the aggregating Serverexample - A.3. A GDS implementation also requires additional behaviour. This section describes automatic behaviour that is required by all implementations of a GDS that supports AliasNames.
