Dear Jim and Jeanne,
I have compiled some changes to Guideline 1.4.  I am plugging through
the new Draft. I really like it.  I need to ask about parts.

My additions are at:
http://www.csulb.edu/~wed/UAAG/G1-4.html

My system for ranking are as follows:

Level A means someone cannot reader without it.
Level AA means that without this access effective readings seriously 
compromised
Level AAA is the right way to do it.

Wayne

-------- Text of the Proposal --------
1.4.1 Configure Text:

The user can globally set the following characteristics of visually 
rendered text content, overriding any specified by the author or user 
agent defaults: (Level A)

     (a) text scale (i.e. the general size of text) ,
     (b) font family, and
     (c) text color (i.e. foreground and background).
     (d) ...NEW... Spacing for inter-line and inter-letter. [To address 
tracking and crowding. This is a level A access property.  Without 
spacing adjustments many visual readers with low vision cannot finish 
documents]

1.4.2 Preserving Size Distinctions:

The user can specify whether or not distinctions in the size of rendered 
text are preserved when that text is rescaled (e.g. headers continue to 
be larger than body text). [NEW] When size distinctions are not 
preserved then the user can choose alternative font family, change color 
(foreground, background) and/or border (style and color).(Level A)
1.4.3 (New) Bounding Container Adjustment

When the user adjusts the text configuration then elements that contain 
text must adjust height so that the text is visible and the selected 
line spacing is preserved. In addition in case of horizontal overflow, 
the user can choose to word-wrap on non-word breaks. This also applies 
to element level changes in 1.4.4. (Level A)
1.4.4 (New) Element level access to configure text ::

The user can set the following characteristics of visually rendered text 
content at the element level, overriding any specified by the author or 
user agent defaults: (Level AA)

     (a) text scale (i.e. the general size of text) ,
     (b) font family, and
     (c) text color (i.e. foreground and background).
     (d) ...NEW... Spacing for inter-line and inter-letter. [To address 
tracking and crowding. This is a level A access property.  Without 
spacing adjustments many visual readers with low vision cannot finish 
documents]

1.4.5 (New) Access to Typography

The user can change the style of every text element to an extent 
equivalent to the style range offered by HTML with CSS. (Level AAA)
1.4.6 (New) Access to layout

The user can change the layout of every element to an extent equivalent 
to the style range offered by HTML with CSS. (Level AAA)
