The problems can be solved by giving each node a "weight" (which I
currently call the Z value) according to which the child nodes of a
given element are arranged. The remaining problem is how to you store
the GUID and the "weight". You can store them as attributes in the
case of elements but what about text nodes? Suggestions on that would
be greatly appreciated.
