ObjectTypes that are not an aggregated, extended or collection ObjectType can only be defined by the MDIS organisation. If a vendor (or group of vendors) determines that an ObjectType might be a candidate for creation as a new ObjectType, the proposed ObjectType needs to be submitted to or proposed to the MDIS organisation. If the MDIS organisation determines that a new ObjectType is to be created, it will be incorporated into the MDIS OPC UA Companion Specification. These new Objects shall be reviewed and validated by the MDIS organisation members.
