Neither "HWG" nor "HTML" is an acronym. (Where I live, "HTML" is sometimes read as an acronym, pronouncing a vowel after each consonant, but even this would not make "HTML" an acronym.) But that's actually a bit different matter, and relates to the confusion between <acronym> and <abbr>. In fact, neither of these elements is of much use, since <acronym> is illogical for most abbreviations whereas <abbr> still isn't recognized by Internet Explorer. Thus, it is _much_ more important to emphasize the need for explicit explanations of any unusual abbreviations, terms, and symbols, in the normal text of a document, or in associated (linked) documents. I've written a relatively long treatise on this: http://www.cs.tut.fi/~jkorpela/html/abbr.html This particular technical issue is in fact an additional (small) argument in favor of my point. The technicality is that attributes cannot contain markup, so you cannot use any tags inside title="...". You could not use e.g. markup to indicate language changes (with lang and/or xml:lang attributes) inside an attribute value. Yet, indicating all language changes is a WCAG 1.0 requirement. (Actually, a requirement which is probably not satisfied by most pages that proudly show an icon claiming conformance to WCAG 1.0.) The ultimate problem is the design flaw in HTML that puts actual content into attributes. (We know that flaw from the alt attribute too: making the alternate content an attribute value restricts it to plain text - no lists, no tables, etc.) But we can avoid that problem when giving explanations of abbreviations simply by not using attributes. When you write explanations as normal content, they are accessible to everyone, and you are not limited to plain text. -- Jukka "Yucca" Korpela, http://www.cs.tut.fi/~jkorpela/
