Hi Aaron, 


      Browsers that have ZOOM on them make the Level AA provisions easy to
conform to.  

 The Level AAA provisions require reflowing the text so that horizontal
scrolling isn't necessary so Zoom won't help you there.   The “enlarge text
font” in browsers would allow users to increase font size but the content
needs to be written properly for this to work.   


Does that help?

I would like to know if the presence of new step-less zooming abilities
(e.g. PageZoom in IE7) will make some of the W3C requirements for font
scaling (like using relative instead of absolute units on web pages) become

If not, if any complaints, please explain or point me to some location where
I can find arguments against built-in zooming techniques in browsers.

We need your input here to give our html-based technologies a definitive
answer if they must use relative units or if they can rely on IE7 for font


I would like to know if something comparable to PageZoom in IE7 is planned
for FireFox 3.
