This field indicates magic properties which are inherent in certain class-specific items. A given class-specific item will (almost) always start with the same set of properties, even if its quality is "normal". Other quality ratings may add more properties to the standard set. It appears that items which will have this field are:
Amazon-only bows, spears, and javelins
Voodoo heads (Necromancer-only shields)
Paladin-only shields
Orbs (Sorceress-Only wands)
