RE: Is there an html or WCAG definition of "modality" as it relates to keyboard behavior in a modeal dialog?

But, WCAG only applies to the web page, not to the browser containing it.

At least that is my take.  If you want a ruling  you might run this past the committee as a whole.  I added the chairs to this email for their information.

Hi Gregg,

If a web page is a context, and moving outside of a web page via the tab key is a change of context, then every web page would fail the WCAG 2.0 criteria as the address bar of browsers (if present) recieves focus after the last focusable element in the page.
