There are many roles that exist that are not actually conveyed by screen readers. Either they're obscure and so seldom used that no one cares if the role is not supported, the content and context are sufficient, or they're overused/misused and having to listen to/read through all the roles would clutter up the content. <dl> lists with their <dt> <dd> elements are fine to use but screen readers rarely convey their roles. a11ysupport.io is not comprehensive and its volunteer data is not kept current but it still offers a sense of the divide between what's theoretically possible and what actually happens. https://a11ysupport.io/tech/html/dt_element https://a11ysupport.io/tech/html/dt_element
