This object type defines the file for a namespace provided by the OPC UA Server.
It represents an XML address space file using the XML schema defined in Part 6 of the OPC UA Specification.
Servers might provide some vendor-specific mechanisms importing parts of an address space as subtype of this object type, for example by defining appropriate methods.
