list-style-type idea

It would be nice to have another possible value for list-style-type, 
namely 'collapsible'.  This would mean that browsers implementing this 
suggestion could display the list in a collapsible tree-view style.

This would eliminate the need for a lot of JavaScript, and would mean 
that what is a relatively common GUI widget could be specified by 
authors with minimal fuss.  It would improve HTML coding, because such 
lists could be marked up with the <ul> element for non-CSS3 browsers.
