Selection following focus means that if you set focus on an element in the
container that it's selected state changes to "true" versus setting the
focus on an element in the container and the author having to apply
aria-selected="true" if they so desire. In the latter case selection
following focus is optional.

Michael and I felt that the UAIG was unclear as to what the user agent
should do in response to focus changes within specific containers.

Hi Rich, et al.

I wrote a reply on another thread, but I think it's apropos here. Also,
adding David B to the To: list.

That's not how I interpret it.  The section in 5.8.3 concerns multiple
selection situations.  The associated table's left hand column is
labelled "Scenario".  That has the sense of a conditional.  Thus, it
does NOT say "selection MUST follow focus". What it says is "*If*
selection follow focus, then the user agent MUST fire the following
events".

Of course, my reading might be wrong.  I didn't write this section. It
was there long before I became editor.  Could those who were there chime
in?

Also, I don't know precisely what "selection follows focus" means. One
possibility is if the author adds an onfocus script that sets
aria-selected to "true" -- would that qualify as "selection follows focus"?
