Talking about screen-readers: How should a screen-reader actually handle
ruby annotations? In this case
<ruby>
漢 <rt> かん </rt>
字 <rt> じ　 </rt>
</ruby>
it would be quite strange if a screen-reader read the annotations,
because they have the same content as the ruby base text. (I hope this
is correct. I don't know the Japanese language, but I understood it as
漢 beeing same as かん only in a different "way" of writing.) So the
reader must not read the annotation.
In an example i got from an older W3C spec, it's different:

<ruby>
  <rbc>
    <rb>10</rb>
    <rb>31</rb>
    <rb>2002</rb>
  </rbc>
  <rtc>
    <rt>Month</rt>
    <rt>Day</rt>
    <rt>Year</rt>
  </rtc>
  <rtc>
    <rt rbspan="3">Expiration Date</rt>
  </rtc>
</ruby>

As this markup isn't used anymore with HTML5, here's how it would be
(dropping the "expiration date"):
<ruby>
10 <rt>Month</rt>
31 <rt>Day</rt>
2002 <rt>Year</rt>
</ruby>
This one now should be read out by the screen-reader. Otherwise the
meaning of the numbers may be not as clear.

(Or is the date-example out-of-date and ruby shouldn't be used there?)
