I disagree. In an appointment, the date IS the content. The metadata
is the markup that identifies the date and its purpose, eg.
class="dtstart".
With an <abbr> the date content is represented in two different ways,
one as prose ("tomorrow at noon"), and once as an expansion. In
prosaic HTML it is valid (and appropriate) to write
<abbr title="Noon, July 3rd, 2008">tomorrow at noon</abbr>
but that's not a suitable machine readable format.
Microformats have properly used <abbr> to expand prosaic dates, but the
syntax has been friendly to neither screen readers nor title popups.
So, the compromise is to have an expansion that's friendly to both
screen readers and title popups, and is also machine readable.
Splitting dates and time into separate <abbr> chunks accomplishes most
of that.
<abbr title="2008-06-30">tomorrow</abbr> <abbr title="12:00">at
noon</abbr>
For those who think this violates the semantic intent of <abbr> I'm all
in favour of a <span title="2008-07-03"> element. This can be combined
nicely with <abbr> for the screen reader and popup crowd:
<div class="vevent">
<span class="summary">
Big blowout lunch party
</span>
<span class="dtstart">
<span class="value" title="2008-07-03">
<abbr title="July 3rd, 2008">
tomorrow
</abbr>
</span>
<span class="value" title="12:00">
at noon
</span>
</span>
</div>
(using the newly proposed date and time value excerpts)
I've put <abbr> inside <span> to speak/display the innermost title
(this needs testing!)
