I don't have any problem with the ABI's goal of making all web pages functional on all browsers. My problem is that it seems to me, from what I've read of the ABI, that they place the burden of achieving this goal almost exclusively on Web page authors. I think the responsibility needs to be shared among three groups: 1. HTML authors must realize that how their pages degrade on various browsers is at least somewhat within their control-- use of the ALT attribute in IMG tags is the quintessential example of this, and there are numerous others. 2. W3C needs to keep in mind, when developing new tags and attributes, how they will degrade on older browsers. (In the 4.0 draft, the TFOOT element is a particularly bad example of this--the requirement is that TFOOT appear before TBODY "so that user agents can render the foot before receiving all of the (potentially numerous) rows of data," but on browsers which don't support TFOOT, this will cause the rows within TFOOT to appear above the body of the table.) But in some cases this may be very difficult, if not impossible--I don't think there could have been any way to write the basic table specs to degrade gracefully. Therefore... 3. Browser designers not only need to follow the recommendation for dealing with unrecognized tags, but also to upgrade in a timely manner to include new, standard tags as much as possible--particularly those which do not degrade gracefully. If 2 and 3 do not live up to this responsibility, HTML authors alone should not have to bear the burden of making sure all pages are functional in all browsers. Chuck
