3.22.1 Abstract Data Model
This section describes a conceptual model of possible data organization that an implementation maintains to participate in this protocol. The described organization is provided to explain how the protocol behaves. This document does not mandate that implementations adhere to this model as long as their external behavior is consistent with that described in this document.
The client security envoy maintains the following GUID data structures, one for each OBJREF_EXTENDED object reference unmarshaled by the client:
domainGUID, which identifies the domain of the computer of the object reference.
machineGUID, which identifies the computer of the object reference.
