Hi Tzviya,

Indeed. Your latter sentence there is what interests me: we can reorder
(and punctuate, and apply font styling) at the style level. That becomes
a matter of writing sufficiently cunning CSS that can match a given
style guide, i.e. it's a SMOP (Simple Matter Of Programming).

I'm not sure — that's why I'm asking :) I mean, I can easily go with the
order that I think would make sense as the semantic order but I want to
make sure I'm not 927ing the space.

On instinct I wouldn't think so. I think it largely boils down to what
order to use, along with some additional notions such as whether
multiple initials stuck together might somehow trip a screen reader
(e.g. Vancouver style would cite this email as from "Berjon RM" which I
reckon might read strangely).

I'd be tempted to go with something like (at 30kft): title, author,
source, date. Without the ontological markup (and with space for
readability), this would look like:

<li>
  <cite>Moby-Dick</cite>
  <span class='punct'>, by </span>
  <span>Herman Melville</span>
  <span class='punct'>(</span>
  <span>Bentley</span>
  <span class='punct'>, </span>
  <time>1851-10</time>
  <span class='punct'>).</span>
</li>

At this point my understanding is that AT is still catching up to ARIA,
I don't think we should be too reliant on it picking up ontologies.

I'm curious which part of WCAG this might violate? Sure enough the
content text is not very explicit, but that's not what you have in mind?

We could switch references between various styles using data-*
attributes and style like the following; but that requires adding data
to the links. I'm not sure it's a good idea — at this point I'm focusing
on the actual citations.

      .refs.numeric a, .refs.author-year a {
        font-size: 0;
      }
      .refs.numeric a::after {
        font-size: 16px;
        content: " (" attr(data-num) ")";
      }
      .refs.author-year a::after {
        font-size: 16px;
        content: " [" attr(data-authyear) "]";
      }

Yeah, I'll point some WAI folks at this thread.
