In my opinion this is a misrepresentation of the status quo.
The reason that no consensus has been agreed for an accessible alternative
to the ABBR pattern is not that no accessible alternatives exist; it is
not that no alternatives have been suggested; and nor is it a lack of
assistive technology support for the suggestions. It is simply that none
of the proposed alternative patterns have been rubber-stamped by the
powers that be.
For example, the following:
<span title="Monday 3 March 2008 (data:2008-03-03)"
class="dtstart">started two days ago</span>
Is perfectly accessible in all tested screen readers (the read the human-
readable "started two days ago") and seems to present no problems for any
other assistive technology. It is trivial to implement -- simply find all
elements (not just SPAN) with title attributes that match the regular
and take the matching sub-expression (.*) to be the value of the property.
It doesn't interfere with the existing ABBR design pattern (which is,
occasionally, used in an accessible manner, such as <abbr class="country-
name" title="Japan">JP</abbr> in hCard) so can be used in conjunction with
it as appropriate; and is highly unlikely to match any false positives on
existing web pages.
There have been other good suggestions too (though none I think as good as
the one shown above) -- it is not suggestions that we lack, but the
inertia to make one or more of them "official" and widely implemented. It
does not bode well for the accessibility of Microformats that one of the
main providers of said inertia has just been banned from the process for
For my part, I've implemented this "data:" prefix in Cognition <http://
buzzword.org.uk/cognition/> and plan on using it when I add hAtom support
to demiblog <http://demiblog.org/>. (hCalendar was previously rolled back
out of demiblog due to accessibility concerns. hCard, XFN and rel-tag are
currently used though.)
