Hi, folks-

I was experimenting with an accessible calculator example. It's still rough,
but one of my goals was to test the focus and navigation syntax of SVG 1.2;
as it turns out, this was something that can easily be done using ASV3/6pr1.

Once again, I want to ask if you intend to include Directional Navigation. I
think it would be a great addition.

I worked up a couple of examples to illustrate what I mean. You can see
them, along with a detailed description with rationales, at:
http://www.schepers.cc/walkingtalkingsvg.html
(Note that it's not necessary for you to have the speech-synthesis plug-in
to prove this point, you can simply look at the SVG bits).

<longStory mode='short'>
* proposal that directional navigation = good, should be in the viewer for
consistancy (maybe overridable)
* demonstration of 2 implementation for directional navigation (auto, and
attribute-specified)
* proposal that if possible, since CSS3 is in CR stage, change directional
navigation to allow nav-index values in addition to/instead of URIs
* proposal for refocus to move a mouse event from a nested element up to its
focusable parent
* proposal to change nav-index to allow for hierarchical navigation (vis a
vis, a parameterized list of integers rather than a single integer as the
value)
* request for more details about what to do when focusable elements are not
visible (display=none, 0 opacity, visibility=hidden, outside current
viewport)
</longStory>

Thanks-
