Hi,
There's been some previous discussion about providing a way to
support tri-state checkboxes, and I recently came across a feature
that's supported in IE and WebKit for this purpose.
The DOM property HTMLInputElement.indeterminate is supported for <input
type="checkbox">
http://msdn.microsoft.com/en-us/library/ms533894(VS.85).aspx
There doesn't seem to be any corresponding content attribute supported
by either.
This was apparently also considered and rejected by the DOM2 WG several
years ago.
