Where does the COE idea come from?

Can NATO “initiate” a COE? As per MC 0685, “A NATO Nation may decide to offer a COE to NATO by formally presenting the offer to the [Chairman of the Military Committee]. That could either be in response to an MC endorsed list or by its own initiative. The MC may, based upon SACT’s advice coordinated with SACEUR, accept the offer and task ACT accordingly to proceed with the development as set forth in this Policy.”
