Yes, section 4.3.4 states that:
"If the value of an instance data node was changed, then the node must be 
marked for dispatching the xforms-value-changed event"
(http://www.w3.org/TR/2005/PER-xforms-20051006/slice4.html#evt-refresh)
So the event should only be marked for dispatching when the node value 
actually changes.
