2.1.1.4.5 Revocation

Prior to initiating registration, the receiver can send the transmitter device a revocation information version (RIV) structure and the WMDRM: Network Devices Protocol CRL as defined in section 2.2.1.6. These messages are sent over UPnP. See section 2.1.1.1 for revocation DRI UPnP mappings.

In addition, the transmitter MUST ensure that the Issue Time of the RIV is current as defined by [CR-WMDRM].
