LM723: Vz in the metal can package

Part Number: LM723

Hi,

It says in the datasheet "For metal can applications where VZ is required, an external 6.2V zener diode should be connected in series with VOUT.", does this mean I should just connect the Vz input to Vout through a diode? Attached is the circuit diagram from page 13 of the datasheet.

Thanks.
