What does the 'D22.1 IVZE' notation indicate on an ILS Rwy 28C Jepp chart?

Explanation:
In Jeppesen approach charts, a DME distance printed with a navaid name shows how far a fix is from that DME facility. The number is the distance in nautical miles, and the navaid name tells you which DME reference to use. So D22.1 IVZE means KOENN (the fix used on the approach) is 22.1 NM from the IVZE DME source (the localizer with DME). In practice, when your LOC/DME reads 22.1 NM, you’ve reached KOENN. This is a distance-based position cue, not an altitude offset or minimum altitude, and it uses the localizer’s DME rather than a VOR.
