If it returns 0, then you could never get the size of an XmlNode (or any class derived from XmlNode) independently of the tree.

IMHO, you should be able to get the mem_sizeof any node (which would include its child nodes, if any) independently of the tree.  If you explicitly ask for the mem_sizeof an XmlTree explicitly, then you'd get the size of the tree object itself plus all the nodes.
