Hmm. It would be nice to use this to update the SMIL accessibiltiy note for a version 2 - use declarative animation (SMIL) rather than Javascript for this, becuase it can be more easily controlled. But there are other things it would be nice to update in that note too, and I don't think anyone has said they have any time to work on it yet. Sigh. Volunteers anyone?

See, for example <http://www.w3.org/TR/smil20/extended-linking.html#SMILLinking-Area>http:// www.w3.org/TR/smil20/extended-linking.html#SMILLinking-Area Here the sensitive region is a volume swept out by a display region X a time range. The time range of a smil:area is its own time container in the hierarchy of time containers. And this is all defined in the SMIL, there is no scripting involved. -- Charles McCathieNevile http://www.w3.org/People/Charles phone: +61 409 134 136 W3C Web Accessibility Initiative http://www.w3.org/WAI fax: +1 617 258 5999 Location: 21 Mitchell street FOOTSCRAY Vic 3011, Australia (or W3C INRIA, Route des Lucioles, BP 93, 06902 Sophia Antipolis Cedex, France)
