Re: @incremental

Steven,

What you say makes sense. However, as an XForms user rather than an implementer I’ve taken it on face value that it only has useful meaning for controls that take keyboard entry like input or textarea and never thought much more about it. That said, you may want to explicitly set incremental="false" on a range control so I can only assume that it’s default in this case would be true. Is that correct or do I have to explicitly set ‘true’ to ensure a live update?

    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?
