Portlet Drag and Drop

[Michelle D'Souza]

Hi Rich,

Yes, we are using aria to communication drag and drop functionality.  
We are using the 'grab' state on items that can be moved and  
'dropeffect' state on elements that are valid drop targets. We are  
also using 'selected' and 'activedescendent' to communicate which item  
has focus.
