ARIA 1.2 will introduce various new roles and mappings for greater parity with HTML.

After publication, we should review the HTML AAM's element mappings and ensure that any necessary elements are mapped to their appropriate WAI ARIA roles.

For instance, del, ins, meter, dl, dt, dd, strong, em, among others and many that will map to ARIA's role=generic but would also likely benefit from continued exposure of API specific information.

EDIT:

list of mappings to track in this issue. generic will be handled separately

• blockquote => <blockquote>
• caption => <caption> and <figcaption>
• code => <code>
• deletion => <del>
• emphasis => <em>
• insertion => <ins>
• meter => <meter>
• paragraph => <p>
• strong => <strong>
• subscript => <sub>
• superscript => <sup>
• time => <time>
