My concern is that urls should be simple and that the content should be reproducable as well as easy to understand. (please do not comment on mine, it's a known disability.) If a 'blind' person was discussing a page with a sighted one, it seems that one is possibly creating an area of confusion. If the pages are generated dynamically this could be unacceptable. eg: about one year ago I was considering buying an Apple notebook and the UK prices quoted online were 50% of market value. Unfortunately(?) they refused to honour these. jay@peepo.com Jonathan Chetwynd Special needs teacher / web accessibility consultant education and outreach working group member, web accessibility initiative, W3C ----- Original Message ----- From: Charles McCathieNevile <charles@w3.org> To: Scott Luebking <phoenixl@netcom.com> Cc: <nir@nirdagan.com>; <w3c-wai-gl@w3.org> Sent: Sunday, January 23, 2000 2:22 AM Subject: Re: XML and accessibility > A simple question can resolve whether there are different needs for > dynamically generated pages And statically generated ones: > > Does the user know for sure whether the page is dynamic or static? > > If the user cannot tell whether there is a difference then there is no > different user need.
