Code sample for doc-glossary requires review and/or revision. Required owned elements may need to be revised based on changes made in ARIA 1.1

The implied role of dt is unclear:

• the normative definition is in ARIA in HTML, which says it has an implicit role of 'listitem':
  https://w3c.github.io/html-aria/#dd-dt2
  *, however, the informative allowed ARIA role attribute value described in W3C’s HTML is 'none'
  https://www.w3.org/TR/html/grouping-content.html#elementdef-dt
• and HTML AAM says it should be mapped using the WAI-ARIA mapping for the 'term' role
  https://w3c.github.io/html-aam/#el-dt

This is discussed in

• DT element change to default role=term (ARIA Working Group Comment) html-aria#57
• DT element change to default role=term (ARIA Working Group Comment) html-aam#78
• Create description (was:definition) list role aria#504
