If you take Can you give me an example here? How can an accessible piece of text say, become usable? Could you resize/scale an accessible piece of text to compensate for an adjustment in say reading distance, and call it usability? I would like to think resizing text is an accessibility feature that should have been there in the first place. > usability to the extreme, as would be the case when faced with a > user who has specific extraordinary needs, then it falls under the > umbrella of accessiblity as defined by WAI.

For example malleability is provided by valid XML right? We can now transform, although we really do have to know our inputs and outputs very well. malleability would be the flexibility that most authors would not like to touch though... I don't want to go to mystical semantic land, if that's what you mean by Malleability. ;) http://en.wikipedia.org/wiki/Venn_diagram I am working on a dia figure: http://www.cs.helsinki.fi/u/hendry/work/thesis/pictures/accessibility.png But I am having trouble intersecting some topics there. I feel I should just use this diagram to put some of the numerous topics I raise in my thesis under the field of accessibility. > And feel free to cross-post to WAI, as this discussion has now drifted > into the realm of human accessibiliy and worthy of mutual consideration. I will post them a message about the definition and see what happens.
