There is...

"This method simulates a package instalation emitting packages required to be installed, removed, updated, reinstalled, downgraded, obsoleted or untrusted. The latter is used to present the user untrusted packages that are about to be installed."

It doesn't really mention anything about ordering or dependencies ?

I'm not entirely sure about the difference between updated / obsoleted,
but I guess the new pkg is "updated", and the old pkg is "obsoleted" ?
All the changeset has is a list of pkgs to install and pkgs to remove.
