I think there are some situations you do not want the attributes to be 
promoted automaticaly. But you want to be able to promote them 
manually.

One case I have in my mind is the symversion attribute. After you have 
checked your circuit, you want to press a button that promotes that 
attribute.

Someone mentioned a separate attribute dialog in the geda-user list.
It may look like this:
--------------------------
already promoted attributes:
  refdes=  [textfield containing "U?]         [deletebutton]
  .....
  .....
availlable attributes inside the symbol:
  symversion=  [textfield containing "1.0"]  [promotebutton]
  .....
  ....
possible other attributes:
  value=   []         [promotebutton]
  model=  []         [promotebutton]
-----------------------------

Well I haven't played with GTK yet, but maybe I'll try that soon.
