For some dynamic attributes, you might want to limit the possible values that are accepted. You can define a choice set that holds a fixed set of choices, and then create a dynamic attribute whose values are limited to the choices defined in the choice set.

Dynamic choice sets aren't associated with a specific namespace. After you define a dynamic choice set, you can use it in any dynamic namespace.

For example, you can define a choice set for colors, with red, blue, and green as the choices. You can select this choice set in the bike_color dynamic attribute in one namespace and use it again in the paint_color dynamic attribute in a different namespace.
