The existing spec. has a caret position in drawFocusRing(); I can't imagine
it supporting a magnifier based on the existing spec.

They're implemented to the existing spec.

They have the shadow dom working, with focus, so that JAWS can read what's
going on.

I'd imagine they can revise it to meet the revised spec, with minimal work;
but should wait until we've reached a conclusion on setCaretSelectionRect,
as it
is intended to interoperate.

      Chuck,

      Is it IE9's focusRing implemented via our changes to it or the
      existing spec?

      Last meeting:

      We reached consensus on " context . drawFocusRing(element) " as an
      improvement to the present whatwg draft.
      http://www.w3.org/2011/01/17-html-a11y-minutes.html

      Ian Hickson originally published drawFocusRing with four arguments:
      " context . drawFocusRing(element, x, y, [ canDrawCustom ]) "
      http://www.whatwg.org/specs/web-apps/current-work/multipage/the-canvas-element.html#focus-management-0


      "canDrawCustom" was dropped, as redundant and problematic.
      "x, y" now defaults to the centroid of the polyline / the center of
      the
      path.

      drawFocusRing has been successfully demonstrated in IE9 preview
      releases
      with the JAWS screen reader.
      Congratulations Microsoft IE Team!
