I think you have misinterpreted the explination of retained mode.
The rule for scene graph changes is:
Changes may be made to a live or compiled scene graph only if the
corresponding capibility bit has been set.
So the answer to your question is that there is no mode which "full manipulation
ability" for a live scene graph. You need to either set the attribute bits or
make your changes when the scene graph is not live.
The capability bits make it more difficult to make changes to the scene graph,
but they also make it possible to optimize the scene graph for much faster
rendering.
