It is in principle possible to define a powerset of any data type. However,
you will need to check if this is supported by the tool you are using.
POWERSET (tNeighbor) is likely to be quite difficult to implement. and I
would not be surprised to find it is not supported.
POWERSET works best with data types that have a relatively low finite number
of values, because it can then be implemented as a bit map.
Have you considered using STRING?
