Notice that with this scheme you can insert any indiviual node under any parentnode just like directories (ie: item 'system' could exist under 'windows' and also say under 'mydir' with all its subdirs or alone or with some of its subdirs).

BTW don't let NodeIds misguide you. NodeId would be unique and in fact A01, AA01 etc goes into another field (ie.NodeText, NodeValue, NodeData..). I used them here for NodeIds just for you to follow.
