Hi again, Thanks for the clarification. I do somewhat appreciate the inherent difficulties that blind users may have accessing online material (my office mate is also blind; he uses a refreshable braille device, and navigates in a 1x40 window using the text browser Lynx). Thanks for reminding us that it is an important issue. You might want to take this up with the wikipedia folks, as they are a larger wikimedia foundation project and surely have more experience with accessibility than wikibooks do. For instance, here is a page of wikipedia accessibility guidelines: http://en.wikipedia.org/wiki/Wikipedia:Accessibility
The wikibook is, and I repeat, fully navigable for the most part but that shouldn't preclude us from striving for perfection.
I think what David was asking was what explicit XHTML in the markup in source would add in terms of accesibility benefits, since the wiki syntax is automatically converted to XHTML anyway for browsing... -- Eric Kow http://www.loria.fr/~kow PGP Key ID: 08AC04F9 Merci de corriger mon français.
