ARIA attributes that have been deprecated for a role must be removed.
Purpose
Not all ARIA properties and states are useful on every ARIA role and starting with ARIA 1.2 certain states and properties that were once considered global have been deprecated on specific roles.
The ARIA in HTML specification defines implicit roles for most HTML elememnts.
The same ARIA property and state restrictions on explicit roles apply to implicit roles.
Information about the element associated with the result.
The information typically includes the tag name, accessible name or other information related to the rule requirements.
"Page" means that the result applied to the page. For example, the rule "One main landmark on the page" is a page level rule.
Element Position
The element position is based on the DOM order of elements in the page.
The element position maybe useful in helping to locate a specific element on the page evaluated (e.g smaller numbers are typically toward the beginning of a page and larger numbers typically toward the end of a page).
Element position 1 is the first element.
The highest element position is the last element.
Element position values for most rule/page results will not be consecutive since a rule only applies to a sub set of elements found on a page.
