Karen, Arved, It is with great sadness that I announce the demise of my much-loved property stacks. Their functionality gradually dwindled away until all they had left was the initial values of all of the properties and the latest specified value. Initial values can be maintained more cheaply in an array, and as the node had to maintain the set of values specified by its attributes anyway, in order to pop the stack, locating the nearest specified value could be done at small extra expense by climbing the FO tree. Considering that the operation is likely to be infrequent, the storage overhead was too great. Requiescant in pace.
