Which element?

[Mr Initial Man]

<acronym>HTML</acronym> <acronym>CSS</acronym>
<acronym>HTML</acronym> <abbr>CSS</abbr>
<abbr>HTML</abbr> <acronym>CSS</acronym>
<abbr>HTML</abbr> <abbr>CSS</abbr>


Which pair is semantically correct?

I'd say #1 but there's been a LOT of discussion on this arcane matter. Abbreviations are shortend forms of words (e.g. Mr., Mrs., dept., etc.), not just sets of first characters.

FWIW, I'd say 4.

I think I see why XHTML 2.0 dumps the <acronym> element.
