* - A single SelectItem
* - An array or Collection of SelectItem instances
* - A Map. The contents of the Map are used to create SelectItem
* instances, where the SelectItem's label is the map's key value,

* map, it is recommended that an ordered implementation such as
* java.util.TreeMap is used.

* The value properties of each of the SelectItems must be of the same
* basic type as the parent component's value.
