In fact, it helps define the term in a way that could generalize to other uses of the term  "accessible content" in other places.   In fact, some people might pick up this usage in other docs.

Creating a special footnote category for an asterisk-version of the term "accessible" would very likely only exacerbate that confusion. Few terms are absolute, actually; and we seem to be straying further and further from clear communication with some of these approaches. However, if this remains too much of a concern, then the approach of using the term "WCAG2-conformant content" seems both clear and non-controversial; and Jan I therefore encourage you to reconsider using it.

GV:   I am already finding many people wanting to define "accessible" as meaning "conforming to some guidelines".   This is a severe problem for all the disabilities and people who are not addressed in these guidelines -- particularly  cognitive, language, and learning disabilities .  (but deaf blind and others as well)

So I don't think we should ever user  "accessible content"   in any formal document -- or as anything other than an aspirational goal.     I thought the asterisk idea was a great way to use this common phrase - yet also bring attention to the fact that it is more than meeting guidelines.  That guidelines are the start - the minimum that you should do. 

Maybe   "minimum accessibility standard"  is a bad phrase since it implies that it only provides minimum accessibility.    What I meant was  "minimum required accessibility"  meaning that you should do AT LEAST this  (not A MOST - or   JUST THIS). 

Maybe we should write   "Basic Accessibility"  but that sounds like  full accessibility to basic functions -- and that is not true.    hmmmmm  What do we say WCAG is that will get across the idea that is it substantial but only the minimum that you should do.  Any ideas anyone?

here is my attempt to fix this -- and address your comment Judy about the old text being too full of negatives.   is this better?:

"Even content that conforms at the highest level (AAA) will not be accessible to individuals with all types, degrees, or combinations of disability, particularly in the cognitive language and learning areas ( From Intro section of WCAG 2.0)".  It is good therefore to use WCAG 2.0 as the basis but to also implement advisory and other techniques to further enhance accessibility where possible.
