 -   **`accessible-placeholder-text`** (_in_ _string_): A placeholder text to use when the item's value is empty. Applies to text elements.
 -   **`accessible-selectable`** (_in_ _bool_): Whether the element can be selected or not.
 -   **`accessible-selected`** (_in_ _bool_): Whether the element is selected or not. This maps to the "is-selected" state of listview items.
--   **`accessible-position-in-set`** (_in_ _int_): The index (starting from 1) of this element in a group of similar elements. Applies to list items, radio buttons and other elements.
+-   **`accessible-position-in-set`** (_in_ _int_): The index (starting from 0) of this element in a group of similar elements. Applies to list items, radio buttons and other elements.
 -   **`accessible-size-of-set`** (_in_ _int_): The total number of elements in a group. Applies to all elements of a group like list items, radio buttons and other elements, but not to their parent container like list views, radio button groups or other grouping elements.
