<snip> The test of a true acronym is often assumed to be that it SHOULD be pronounceable as a word within the normal word patterns of English. By such a reckoning, BBC is not an acronym but an abbreviation; whereas Nato ( = North Atlantic Treaty Organization), being pronounceable like Cato, is an acronym. </snip> The original post concerned the use of the <abbr> and <acronym> tags. The pertinent question now that the definitions are settled: how should speech-readers render an <acronym>? At one time a "pronounce" attribute was proposed, then dropped. <acronym pronounce="no">XML</acronym> but we know now that XML is not an acronym. Speech-readers will probably read the title attribute, so would you code <acronym title="Portable Network Graphic">PNG</acronym> or <acronym title="ping">PNG</acronym> ? Just curious.
