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. or 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 change. or 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!
