</li>
<li>All elements having an accessible object in IAccessible2 mapping are supposed to implement IAccessible, IAccessible2 and IAccessible2_2 interfaces.</li>
<li>
User interaction with certain HTML elements will set an element's <a data-cite="html/form-control-infrastructure.html#concept-fe-dirty">dirty value flag</a>. These elements, as identified in [HTML], could have attributes that represent the default value or state of the element. When the dirty flag is set, that default value or state does not necessarily determine the value or state of the element or corresponding accessible node.
