My problem is; strong and em do draw attention as well don't they? I mean normally they do by some sort of mechanism (visual or aural).
Sure they do, as do headings, and images. But the purpose is different. Whereas headings, objects, emphasis etc. are usually an integral and static part of a document, the M/MARK/HI/FLAG/ATTN elements may change.
Secondly, attention which is caused by a visual, aural or shortcut clue sounds like presentational markup to me.
Somehow these points of interest surely have to be presented, but they are more than merely presentational. -- Jens Brueckmann http://www.yalf.de
