I believe the better way to do this is to use a "multibox" tag, instead of a
"checkbox" tag.  I almost wonder sometimes whether the need for "multibox" is
larger than "checkbox".  I don't have enough experience building applications
using these to really get a feeling for that.  I would think a very useful
enhancement would be a "NOTE:" in the "checkbox" documentation saying that you
should likely use "multibox" if you are tending for your "value"s to be
attribute or capability names, as opposed to "on" or "yes".
