I have for several years have been using the following on a few  
important documents (such as my CV):

<abbr class="initialism|truncation|acronym">
<acronym> = a sub-type of abbr

Which is styled by

abbr, acronym { font-style: inherit; border-width: 0; }
@media aural, speech, spoken
	abbr, acronym { speak: normal; }
	abbr.initialism { speak: spell-out; }
	abbr[title].truncation { speak: normal; content: attr(title); }

I considered <abbr class="acronym"> and <acronym> the same, but used  
the latter on most pages because of WinIE.
