The GDS should automatically remove any instances of AliasNameType and AliasNameCategoryType that are associated with an unregistered Server. However, the AliasName instance or AliasNameCategory instance could be from multiple Servers and should only be removed if all of the Servers that referenced it have been removed. The GDS shall remove any AliasFor References that point to the unregistered Server. The GDS shall delete the ServerUri of the unregistered Server from the ServerArray Property. Figure B.3 illustrate the unregister process in a GDS.
