Hi James,

I'm more concerned about a link in that hidden frame, or perhaps 3 or 4
links, and how/what will happen with tab-focus.  For a screen reader to be
able to afford the user the ability to fire a link, it must first receive
tab-focus. Yet those tab-focusable links are hidden to the sighted user.

How do you reconcile that with: 2.4.7 Focus Visible: Any keyboard operable
user interface has a mode of operation where the keyboard focus indicator is
visible. (Level AA)
http://www.w3.org/TR/2008/REC-WCAG20-20081211/#navigation-mechanisms-focus-v
isible

I have posed this question numerous times now, and never received an answer
(it is also the basis for my current Formal Objection towards the Issue 204
Decision, where those "links" can now apparently be hidden and still
semantically rich - i.e. active.).

Cheers!

JF
