 -   [User interface component](https://www.w3.org/TR/WCAG22/#dfn-user-interface-components) is a part of the content that is perceived by users as a single control for a distinct function. User interface components include form elements and links as well as components generated by scripts. This test uses the term "user controls" for brevity.
 -   The accessibility properties of the user control must be correct if the user control changes.
 -   Per [WCAG 2.2 Understanding SC 1.4.1 Use of Color](https://www.w3.org/WAI/WCAG22/Understanding/use-of-color) authors cannot set the visited state of links. The anchor element does not include a "visited" attribute; therefore the author has no ability to alter the state through an attribute setting. Exclude visited/unvisited state of links from this Baseline test.
+-   [Widget Roles of Accessible Rich Internet Applications (WAI-ARIA)](https://www.w3.org/TR/wai-aria/#widget_roles) lists roles that may be used for user controls. A "widget" is a "discrete user interface object with which the user can interact. Widgets range from simple objects that have one value or operation (e.g., check boxes and menu items), to complex objects that contain many managed sub-objects (e.g., trees and grids)."
+-   [Widget Attributes of Accessible Rich Internet Applications (WAI-ARIA)](https://www.w3.org/TR/wai-aria/#attrs_widgets) lists state and property attributes for user interface elements found on GUI systems or in rich internet applications which receive user input and process user actions. These attributes are used to support the widget roles. The WAI ARIA specification explains "the values of properties (such as aria-labelledby) are often less likely to change throughout the application life-cycle than the values of states (such as aria-checked) which may change frequently due to user interaction." 
+-   In the Baseline Test instructions, where an ARIA role is identified, it is the first valid ARIA role attribute value.

However, there are certain scenarios as described in the tests where the author's determination would be incorrect." |
