Widgets 1.0 - widget settings: publishing / modifications

Not sure if the issue was previously discussed - 
I could not find its trails anyway..

If I understand correctly, the purpose of the following API 
functions preferenceForKey / setPreferenceForKey 
available on Widget interface is to query widget runtime for 
"widget instance" - specific settings. 

Then several questions/issues come:

1) will there be a "setting" element available 
   in the configuration file for the purpose of publishing 
   widget settings? (Widget runtime could then, for example, 
   provide a consistent UI for editing settings)

2) how a widget will then be notified on settings changes 
   made from the widget runtime UI?
