         If I understood what you said, you are saying that the final 
holdup on using animations and graphics isn't in 3.4 but in 4.4 ... I never 
did understand what was being said in 4.4 so your comments are helpful, if

If 3.4 used the term "illustrate", as I have suggested in the past, it 
would be clear that 3.4 is NOT new content but equivalent content. And, I 
am not telling users who could benefit from the content to turn it off, 
only those for whom it is any type of a distraction, annoyance, bother, 
nuisance, etc. Those who benefit from such content are not going to turn it 
off, but they cannot turn on what isn't there.

We cannot mandate quality in text or in illustrations. We can mandate 
"clear and simple language", but that does not in and of itself insure 
quality in any direction. We cannot mandate the quality of illustrations, 
we can only state what the minimum sufficiency is. And the minimum, is one 
per page. A minimum of zero per page doesn't serve the checkpoint, and 
stating a sufficiency criteria in other than normative quantities seems to 
cause problems.

Matt, according to the above, 4.4 as you have described it's application, 
is clearly "an artificial barrier that keeps authors from using their own 
knowledge of their subject matter to make better decisions". The decision 
you give authors now with 4.4 is either do the website so it suits your 
available content and intended audience, or make it "accessible" to 
everyone but your intended audience.
