2.2.3 Context ORPC Extensions
Context ORPC extensions are specified in [MS-DCOM] section 2.2.21.4. These extension formats are passed as out-of-band data on ORPC calls. Each individual extension is identified by a "policyID" of its corresponding EntryHeader ([MS-DCOM] section 2.2.21.5). A Context ORPC extension must be contained in the PolicyData array element ([MS-DCOM] section 2.2.21.4) corresponding to the EntryHeader array element ([MS-DCOM] section 2.2.21.5) that contains the policyID of the Context ORPC extension.
