Icons for expand/collapse and n/a

The expand/collapse icons I was thinking of this
morning are at
http://www.w3.org/International/icons/open-thin.gif
and
http://www.w3.org/International/icons/close-thin.gif

They seem to be quite small, but since they're nothing
but straight lines, they should expand perfectly to any
size we want. I might even be temped to try using just
the characters [+] and [-], since they'd expand with
the rest of the text.

I've looked for icons that would express "NA" visually
-- haven't found anything -- not surprising since this
really isn't a very visual concept. IMO probably best
just to use the (text) letters.
