2.2.18.6 OBJREF_CUSTOM
This form of OBJREF is used by a server object to marshal itself into an opaque BLOB using a custom marshaler. The custom marshaler is a COM object that can marshal and unmarshal the data contained in the BLOB. The CLSID of the custom marshaler object's object class is specified within the OBJREF.
If the interface specified by the iid field of the OBJREF structure contained in the OBJREF_CUSTOM has the local IDL attribute (section 2.2.27), the OBJREF_CUSTOM MUST represent an object that is local to the client that unmarshals the object.
