while i agree with scott, we cannot dictate the technical approach as long as the user is covered. with personalization and content management, you could visit a site and select all content be delivered to you in a particular format. Universal Design is a good concept, but hi-end marketing requires personalization and your ad revenue and catalog sales are what keep you a float. Therefore, I can use a database to push the content that you desire. Many sights already do this and you may or may not be aware. A most excellent tool is Vignette Story server. The objective is to turn hits into revenue and database driven web sites support this. they also support ease of use with content maangement tools. Remember, the commercial market and print newspapers and magazines are going to be the toughest to convince. i also must caution the use of database driven web sites if they are going to see a lot of useage. this is an operations issue and would hope that the operation folks are up to speed on caching and scalability and running a hi-end site. Depending on the operating system, middleware and dataabse, a methodology could be used to generate the page and cache it so it does not get hit. One thing that bothers me with validators, bobby and other tools is they always tell you when you need <noScript>, but they do not take into account if the user has turned javascript off on the client side then the server side validation kicks in and the information is processed. there is so much testing to be done to rally quantufy how each tool and browser work with agents. all this in the time to market that uses internet time. i do not think the WCAG guidelines have deifned their target audience. Is it PWD or developers - it should be both! They have a simbiotic relationship, yet each have different subgroups. Hence different requriements and needs. Universal Design is supposed to be a cure all, but when? three years? thisnk we need to putn the marketing caps on and use the soft sale appraoch...hook the developers with a nibbel and then when authpring tools are on board, then use the net! see y'all next monday in los angelos. rob ----- Original Message ----- From: Scott Luebking <phoenixl@netcom.com> To: <charles@w3.org>; <phoenixl@netcom.com> Cc: <w3c-wai-gl@w3.org> Sent: Sunday, March 12, 2000 8:27 PM Subject: Re: A proposal for changing the guidelines > Hi, Charles > > I'm not sure you're understanding my point.
