ol and ul elements must only have grouping role values of directory, group, listbox, menu, menubar, presentation, radiogroup, tablist, toolbar or tree. NOTE: Deprecated in favor of HTML 3 a more general rule on role restrictions based on ARIA in HTML specification.
The ol and ul elements have role restrictions as part of their definition in the W3C HTML5 Specification.
When ol and ul elements only need to use the role attribute when they are part of interactive widgets and are restricted to widget grouping roles.
The role values used identify grouping widget roles to ensure that their native grouping semantics are not inadvertently overridden by non-grouping widget or landmark 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.
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.
