While we are talking about the DL, I would like to bring up an existing
issue again. That, DL as a list is currently lacking of list item inside of
it. That causes two issues:

1) paired DT and DD have no way to be grouped so from the perspective of
meaningful HTML codes they aren't really "paired";

2) web developers are forced to use other two more inappropriate list
elements like UL or OL because the lack of list item inside DL causes
inconvenience when it comes to styling, or they have to resort to
javascripting to dynamically add <li role="presentation"></li> into DL
which doesn't work in non-javascript environment.

For the love of god, please let LI also be DL's child. Thanks all.
