Handling Multi-Value Slots

Up to this point, the slots we’ve defined only accept a single value per slot: one destination, one departure date, and one return date. But sometimes you need to collect a list of values in a slot rather than a single slot value.

With a small tweak to a slot definition, we can specify that a slot is able to accept a list of values. To illustrate how this works, suppose that we want to add an intent to the Star Port 75 skill that lets a user state their favorite planets. Such an intent might be declared in the interaction model like this:

{
  "name": "FavoritePlanetsIntent" ...
