As I recall, the netlister will find one of the elements and deem it to
be that object. The netlist backend queries attributes by refdes name,
and those names are used to lookup in a hashtable mapping name ->
OBJECT. This leads me to strongly suspect that you should copy all
attributes which the netlister might care about into all slots.
