ARIA roles for Identifying title panes

A title pane is a container with a title bar, clicking the title bar 
expands and collapses (hides/shows) the container and its contents.  My 
thought it so put the title bar into the tab order via tabindex=0 and use 
the enter key in addition to mouse click  to toggle hide/show of the 
associated container. 

I am uncertain as to what ARIA roles to use.   I was not going to put the 
container itself into the tab order but the container seems to be the 
element which should get the region role and a state of expanded = true or 
false.   I don't know what role the title bar itself should get but it 
does control the container. 
Thoughts?

There is a test page for a mouse only version  (NO keyboard support has 
been implemented yet) of this widget available in the Dojo nightly source:
