Base Info ServerType

The ExportNamespace Method provides a way to export the namespace from the Server AddressSpace to the XML file represented by the AddressSpaceFileType. Value Attributes are only exported if they represent static configuration information. The client is expected to call the ExportNamespace Method first to update the XML file and then access the file with the Methods defined in the FileType.

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