I tend to agree with Flavell. I also have a followup question. I think the guidelines should have some kind of "deprecated" guidelines. In order to help authors to fix their old pages, or to help authors who will never bother writing stylesheets for non-visual media. (only a minority is writing those for screen) Many authors can't afford being "perfect" and one should find a way to help them (see Chris Hasser: Censorship by laziness) The deprecated guidlines in question include the following: Many authors use HTML art (a cousin of ASCII art) to do decoration to their pages (I know it's bad). the question is how to make it "invisible" to non-visual browsers. In images, writing alt=" " seems to work (for Lynx at least) Should HR title=" " do the job for a HR used to underline a heading? The answer depends on how non visual browsers present HR, when it has a title. Do they just present the title or do something in addition? Mentioning HR, should an IMG serving as real HR have the ALT as the guide lines propose for title. E.g., ALT="Footnotes" ? I think so, no? Flavell correctly deprecated ALT="-----------". I think that HTML art is going to increase, since the comercial community is worried about bandwidth, and ways to reduce the use of images. People are hesitent with stylesheets due to slow and buggy implementation, as well as the need for the author to understand complicated concepts like inheretence and cascading order. I saw in Web Review an article proposing to use HTML art by making some drawings with tables. The idea is to make a grid and paint the different cells with different colors. overall this method could be speech friendly. It is evidently Lynx friendly (up to a possible strange space). The question is what a non-visual browser will do with a table whose cells have only nbsp in them? Will it make some "noises" (speech browser)? e.g. [TABLE] as Lynx writes [IMAGE] for an image without an ALT attribute? ( I know I can hide the table with a stylesheet, and make it important to be on the safe side, but 99% will never write a stylesheet for the non-visual media, at least in the near future.)
