How to create a zone in which only the specified item ids are allowed

[Deazer]

Parameter: zoneAllowedItemIds
Example:

    <zone name="[queen_ant_epic]" type="epic" >
        <set name="zoneAllowedItemIds" val="7575;7676;7576" />
        <polygon>
            <coords loc="-23176 185080 -6000 -5500" />
            <coords loc="-20104 185080 -6000 -5500" />
            <coords loc="-20104 177928 -6000 -5500" />
            <coords loc="-23176 177928 -6000 -5500" />
        </polygon>
    </zone>

Thus, only id 7575 id 7676 id 7576 items will be available to use in the zone
