Parent roles can be defined using the HTML DOM structure or the aria-owns attribute.
Required parent role is a DOM ancestor of the element.
Required parent role references the element using the aria-owns attribute.
NOTE: HTML DOM parent/child relationships for defining relationships is preferred over the use of aria-owns attribute, since it is less likely to result in authoring errors associated with creating and referencing elements with unique ids.
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.
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.
