           Summary: DataTransfer's setData() and clearData() should return
                    booleans
           Product: HTML WG
           Version: unspecified

These methods from
http://www.whatwg.org/specs/web-apps/current-work/multipage/dnd.html#the-datatransfer-interface
are currently spec'ed as void, should return a boolean value indicating whether
the operation passed or failed. 

This is how Microsoft has spec'ed these methods:
http://msdn.microsoft.com/en-us/library/ms536352.aspx
http://msdn.microsoft.com/en-us/library/ms536744.aspx
and while it's not a feature most scripts will make use of, it could be useful
if for example a web application expects to run on a platform where the memory
available for clipboard operations is limited, or where another application may
have locked the clipboard when the setData()/clearData() method is called.
