goodwill,
I interpet "hanging luminaires" to include sconces. it just hangs from the wall, not the ceiling. IMHO, nothing should be in "the zone". this topic has been beaten to death in the past, so I'll just leave it at that.
While you may interpret it that way, the code making panel has statements in the ROP and ROCs that say other wise. I don't have time to dig them up, but they have specifically stated that a wall fixture is permitted in the zone.
