@_Ben_ found this awhile back, i have no clue if it could work with other things then nationality
it seperates them by ,
<widget class="db_record_list_text" id="intc" alignment="right,centre_y,can_scale" font="title" colour="text" icon_enabled="true" >
<record id="object_property" dont_set_hint="true" get_property="PNal"/>
</widget>
