Hi Thomas, When you say uniquely mark a node, for what purpose? Do you need to serialize this mark?
In general I'd say the Node pointer itself uniquely identifies it. Is this not sufficient? Alternatively you can attach a custom UserData object to the Node via its s/getUserData method. Or as you suggest use the DescrptionList on each Node. Robert.
