A data template that is used to generate arbitrary data of a user interface element that is part of the hierarchy of user interface elements used to render a user interface. The data template is used to generate the arbitrary data of the user interface element, even though that component is not also a user interface element. This contrast with the use of a user interface template which is used to generate the user interface element itself. This permits for greater control in defining the layout, content, and/or the look and feel of portions of the user interface element.
