I'm a little confused.  If you don't want the user to have to go to the 
external state-manipulation tool, then why not use 
checkout-unlock-checkin?  I would think you would want the checkin to 
happen when editing is done, to publish the state.  Also note that the 
state is "published" regardless, in that any changes made by any client 
are visible on the resource checked out, whether or not it's checked in 
again -- it seems pretty clear in this case you're talking about 
in-place checkout.

The auto-version property is a bit of a hack to deal with 
non-DeltaV-aware clients that can never know when to check out and 
check in.  Adding more values to this property runs a risk of confusing 
DeltaV clients that are aware of this property but only know the values 
in the initial standard.  OTOH I'm not aware of any clients at all that 
use the value of this property as yet so it would be good to hear if 
there are any.
