Only in Pedantic Bizarro Land. Come on, Daniel. There are no manufactured nodes. Those two are the final nodes, after a bit of parent rearrangement. We are not making up A2 or X2, as in Philip's original email. The commit process is not creating nodes that exist only during the txn. All nodes survive the txn. Why are you being pedantic here? I see it as argumentative, rather than constructive. :-( Cheers, -g
