Hmm. This parameter is not in the current spec and is not in attica or GHNS 
supported at the moment and makes it incompatible with clients like the MeeGo 
Installer an other servers like Maemo garage or others. It also problematic if 
the user only wants to update a subset of the available updates
The current update system works via the version field where the client compares 
the current installed version with the available version and offers a possible 
upgrade to the users.

It´s always possible to extend this functionality in the next version of the 
spec if you want but this should be discussed on the ocs list and we need a 
consensus between all the parties.

I think it is important that all the available clients and servers stay 
compatible.
