I think the reason for not including "type" attribute in HTML is
that one shouldn't ever refer to anything by textual label only -
we're using HyperText Markup Language so the only way to refer to
something should be in form of hyperlink.
The above example should have markup such as
<li id="quizanswer">All of the above</li>
<p><a href="#quizanswer">Correct answer is ...</a></p>
and the UA should take care of the rest. Activating the link should
highlight (or indicate in some other way) the correct answer because
it's the target of the activated hyperlink.
As long as the (X)HTML WG believes that this is how the world should
work, there's no way we can get the fix in the HTML specification.
This problem has been discussed many times before and there're cases
where one needs more complicated item markers than 1,2,3 or a,b,c.
An example could be "§1, §2a, §2b, §3, ...". Such thing would still
be an ordered list but there isn't a good way to mark up such a
content to have semantics of a list. We would need a <ol> (ordered
list), <li> (list item) and <lim> (list item marker) and then we
could do something like this:
<li><lim>§1</lim> first item</li>
... as defined in §1, we can ...
It would be up to UA, where the contents of <lim> element should be
rendered. It could be rendered to the "normal bullet point position"
or CSS could be used to give a hint about the author's recommended
