data-dojo-id creates object reference of the widget. Though TodoMVC application does not have multiple instances of this widgets-in-template, "${id}_" prefix is added to data-dojo-id attribute to avoid ID duplication.

The todo UI, composed by repeating <li> for each todo item with dojox/mvc/WidgetList.
Each <li> is created along with a widgets-in-template associated with it.
Each widgets-in-template here does:
- Associate completed attribute to the existence of "completed" CSS class of its root DOM node (Such association is used by todo/_CssToggleMixin code)
- Associate hidden attribute to the existence of "hidden" CSS class of its root DOM node (Such association is used by todo/_CssToggleMixin code)
- Mix-in in todo/_CssToggleMixin as well as todo/ctrl/_HashCompletedMixin, so that the combination of URL hash and todo item's completed state will end up with the shown/hidden states being updated (by adding/removing "hidden" CSS class)
- Bind its uniqueId attribute to the data model for the todo item, so that the action handler for removing a todo item can specify which todo item should be removed
- Bind its completed attribute to the data model for the todo item, so that todo/ctrl/_HashCompletedMixin code can determine the shown/hidden state with the URL hash
- Bind its hash attribute to the todo/ctrl/RouteController instance, so that todo/ctrl/_HashCompletedMixin code can determine the shown/hidden state with the completed state
The value attribute is associated with the text in this widget, and bound to the todo/ctrl/TodoRefController instance, so that the count of incomplete todo items is updated as soon as todo/ctrl/TodoRefController obtains the data from Dojo Object Store.
The single attribute is associated with the existence of "plural" CSS class of its root DOM node. (Such association is used by todo/_CssToggleMixin code)
The single attribute is bound to the todo/ctrl/TodoRefController instance, so that the state whether the count of incomplete todo item is less than or equal to 1 is updated as soon as todo/ctrl/TodoRefController obtains the data from Dojo Object Store.
