I have an additional discussion item for Guideline 3.2 that I would like 
to raise before the next draft.   Should I create a bugzilla entry?

I raised concerns to the list that Success criterion 3.2.1 is too 
restrictive [1].   I provided a keyboard accessible version of a tab panel 
that I believe is accessible and behaves in a predictable manner but would 
fail 3.2.1.  Gez commented with a proposed change to 3.2.1 wording [2].  I 
have modified Gez' suggestion and would like to propose the following new 
wording for 3.2.1:

Option 1: When any component receives focus, it does not cause a change of 
context, except where the change of context could be considered the 
expected behavior of a user interface component.
Option 2: When any component receives focus, it does not cause a change of 
context, except where the component defines the intent of the focus 
Option 3: When any component receives focus, it does not cause an 
unexpected change of context.   Note: I suspect folks will object that 
"unexpected" is not testable. 

I am also concerned about 3.2.5, Changes of context are initiated only by 
user request,  since it has some of the same issues.   But, I believe that 
arrowing to a new tab in a tab panel control is considered  to be 
"initiated by user request" as long as the user knows that the component 
with focus is a tab panel control. The expected behavior of arrowing 
between tabs in a tab panel is to show the contents when each tab receives 
focus.    If this is true, the currently Level 3 SC would allow my tab 
panel example while the current level 1 SC would not!
