Device not supporting I&M5 still include "OEM Device ID" suboption in the DCP device option list (certification issue)

According to specification if device does support I&M5, it has to support the device property  "OEM Device ID", that can be read with DCP (DCP get/request/option=2/suboption=8) or reported in "ident all response".

The issue is that devices not supporting I&M5 still report the "OEM Device ID" suboption in the DCP device option list by "ident all response" (DCP option=2/suboption=5), (frame 3). On request to this "OEM Device ID" with get request reports the device incorrect data (s. frame 13).

Only implementations that do NOT want to use I&M5 are affected by this issue.
