+Autocomplete Actions and Key:Value Pairs
+----------------------------------------
+
+Remote Autocomplete widgets may receive items using key:value pairs. The key 
+of the currently selected item will be available in a hidden input field.
+
+This also allows the Autocomplete Widget to receive JavaScript Actions as 
+selectable items. These Actions will not be validated client-side,
+but rather be available at all times.
+
+Item types can be mixed and matched in one widget. Make sure to adjust your
+backend validation method for filtering multiple types.
