We are doing some wheel re-inventing, here. Unfortunately, it is not possible to get everyone talking to have read everything that was ever written. On the other hand, the WAI has a User Agent Accessibility Guidelines docuement in Candidate Recommendation status as we speak that attempts to make this protocol clear. If _that_ document is something that we can't agree on, we need to take this up with the UA working group and The Director. Both the author and user participation in the show/hide control process is important; the protocol shows how they work together. The plot is sometimes summarized as "author proposes, user disposes." A slight expansion on that is laid out in some comments to the Device Independence group prepared by WAI/PF. some WAI comments on Device Independence <http://lists.w3.org/Archives/Public/www-archive/2001Nov/0069.html>http:// lists.w3.org/Archives/Public/www-archive/2001Nov/0069.html The Recommendation track language of record in this are is the checkpoints of UAAG Guideline 2: 2. Ensure user access to all content. <http://www.w3.org/TR/UAAG10/guidelines.html#gl-content-access>http://www. w3.org/TR/UAAG10/guidelines.html#gl-content-access Throughout all this we need to constantly affirm that the author's sense of what is important is extremely valuable. It saves many users much wasted time and helps some users understand what they would never find their way to if they had to do all that filtering and profiling themselves. But it is not globally accurate. The author cannot fully appreciate the communications usefulness or uselessness of all aspects of the data bundle in all the far nooks and crannies of the user-capability space. So in the end, the user has to have the chance to attempt to resurrect a situation that is not working by piecewise control of this control variable (see Guideline 2.3 in the UAAG CR version). We have consistently maintained that no data should be shared with the user's agent that is not open to the user. What is easy should be easy, but what is hard should be possible. After some careful consideration, this principle has been accomodated in a change to the SMIL specification in the area of the 'override' attribute on the customTest element. <http://www.w3.org/TR/smil20/smil-content.html#adef-override>http://www.w3 .org/TR/smil20/smil-content.html#adef-override Al At 11:11 AM 2002-01-31 , Joel Ward wrote: >Hi Kynn, > >I agree about that.
