My initial thoughts on these comments...

JR: Maybe we could go back to being more specific. Maybe rewording as: 
SC: The authoring tool must allow the author to specify font family, 
text scale, foreground color, background color, magnification (e.g. for 
graphics and spacing between text) by one of the following methods: (1) 
inherit these settings from the platform, or (2) include these settings 
within the authoring tool's own preferences with the same 
configurability range as the platform.

JR: Good idea to look at "analog, time-dependent input".

JR: I don't think I agree - if I set up different control keys etc. I 
would expect them to be saved.

JR: Maybe we need a new SC dealing with this since clearly connect 
time-outs are different from the actions of collaborative authors.

JR: So is search but it is in ATAG because it is additionally important 
to users with certain disabilities. If we take it out, and a tool 
doesn't do it, we have no way of saying there is an accessibility problem.

JR: There may be others, but we require these.

JR: We do talk about "reversible actions" - maybe we should define this 
term.

JR: Follow? Implement?

JR: Maybe this is because it would take an outsider too long to test?

JR: I'd like to discuss this more. Barry, any thoughts?

JR: Well, technically, they aren't guaranteeing they always produce 
something that meets WCAG 2.0 for example. Instead they are saying they 
meet a Benchmark document (that they can write) that is based on WCAG 
techniques.

JR: It depends on how smart the tool wants to be about it. The tool can 
handle purely decorative non-text content without asking the user at 
all, some alternatives can be pulled from other sources (B.2.4), and 
special-purpose UI's can be built to make adding ALT easier.


> B.2.4 Why do we need this if we already have B.2.2 (both seem overly

JR: Because it is important that tools don't try to make up their own 
alt text - e.g. from file names etc..
