Base Info ServerType

The ExportNamespace Methodprovides a way to export the namespace from the Server AddressSpaceto the XML file represented by the AddressSpaceFileType. Value Attributesare only exported if they represent static configuration information. The client is expected to call the ExportNamespace Methodfirst to update the XML file and then access the file with the Methodsdefined in the FileType.

Serversmight provide some vendor-specific mechanisms importing parts of an address space as subtype of this ObjectType, for example by defining appropriate Methods.
