Hi Ian, an answer that is very ahort, and one that is very long: short: Yes, SVG should let you get the content out of a presentation, and enable the same things as flash. Of course it depends how it is used, so it is important that authors and tools follow approriate accessibility guidelines. long: There is a W3C Note that I co-wrote called "Accessibility Features of SVG" that describes some of this and how to do it in detail at http://www.w3.org/TR/SVG-access cheers Charles McCN On Thu, 20 Dec 2001, SHARPE, Ian wrote: Apologies if I've not picked up something but it sounds like XML/XSLT + SVG (mixing in one "page"?) combination could be where browsers are heading? I was originally thinking that SVG could be an opportunity for the visually impared to possibly get some useful information from a graphical presentation? I know it's been said that it is not a Adobe replacement for Flash but if I use flash as an example then we are talking about something which is completely inaccessible correct? It obviously doesn't make sense to provide an actual alternative but if we could even get the information out then that would be an improvement? I recently came across 3 fantastic offers on books but they were in Flash and so completely useless to me. Is it possible or likely to be possible to say get the text from such a book if it were in SVG format? I'm concerned that we might be missing an opportunity to possibly define specific standards (as opposed to the general guildelines given in the SVG specification on Accessibility) before SVG becomes more commonly used? I'm getting the feeling that my fundatmental lack of understanding of exactly what SVG is and how it works may be letting me down so apologies if the above is simply rubbish!! But my concern is genuine.

I draw some conclusiions from that. Necessity to support PDF (Acrobat) is still questionable to me. PDF is not W3C standard/recommendation, and is based on PostScript which is good but aged technology. I think XML+CSS, plus SVG for vector-based pictures suites needs of modern desktop much better than PDF. Besides, missing PDF/PS support in Windows is not critical at all - as you can install GhostScript and it will do all this stuff for you. To prevent (possible) questions about Linux - GhostScript comes as standard with all major Linux distributions, and KDE/QT uses it for printing and "printing to PDF" (PDF generation) My major concern with Microsoft is SVG support. MS supports XML and (partially) CSS2, and there are even some CSS3 properties implemented. XHTML support is not listed among "available features" of MS IE, but so far it works ok. If MS is kind enough and can add SVG to MS IE - it would be great for everyone. | | > Without wide availability of SVG plugins (or other form of SVG | > support), this wonderful specification/standard will fail (or go to | > niche markets) | | This is why I tend to qualify reservations about SVG by "if it becomes | widely adopted".

That's what I was keeping in mind speaking about Microsoft. I wrote "plugin" but exact packaging of "SVG-enabler" application is not so important. Adobe's plugin for MS IE/Windows is an ActiveX control, if I remeber correctly. But it works also with Netscape6 if you copy 3 DLL's manually to Netscape's Plugins directory. Was my second mail (clarification to first one) is again not clear enough?.. Than I probably should switch to Russian ;-) -- Charles McCathieNevile http://www.w3.org/People/Charles phone: +61 409 134 136 W3C Web Accessibility Initiative http://www.w3.org/WAI fax: +1 617 258 5999 Location: 21 Mitchell street FOOTSCRAY Vic 3011, Australia (or W3C INRIA, Route des Lucioles, BP 93, 06902 Sophia Antipolis Cedex, France)
