"incremental
  Author-optional attribute that defines when instance data is updated by a  
control. Controls with bindings normally update the instance data when the  
control loses focus. When true, this attribute indicates that the control  
should update the instance data more often, thereby generating additional  
xforms-value-changed events. In incremental mode, an implementation may  
buffer sequences of changes happening in quick succession, and apply them  
all at once. The default value for this attribute is false. Although this  
attribute is available for all controls, in some cases there may be no  
perceivable difference between incremental and non-incremental mode."

I think that the default value is wrongly described. In fact many controls  
are incremental, in the sense that something happens without the control  
losing focus.

Non-incremental:
   input, secret, textarea
   upload?

Incremental:
   output
   range (?)
   trigger/submit
   select/1

What do you think?
