The GDS should automatically remove any instances of AliasNameType and AliasNameCategoryType that are associated with an unregistered Server. [Note: the AliasName instance or AliasNameCategory instance might 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-10 illustrate the unregister process in a GDS.
