3.1.5.3.1 InitiateRegistration Function
The device MUST perform the following steps to complete the InitiateRegistration function:
Collect the WMDRM-ND device certificate and the root device ID stored in the extender device.
Pack the certificate and device ID information into a DSLR request message blob (refer to [MS-DSLR] section 2.2.2.1 for the message syntax).
Invoke the RegistrationRequestMessage request using the remote function proxy on the host, passing in the message blob as an input parameter.
Wait for the RegistrationRequestMessage response with the return code from the host.
Return the final result code by sending the InitiateRegistration request to the host.
Once the InitiateRegistration function returns, the device waits for the next request from the host.
