Unfortunately I don't think there's any good opportunity there. While locality of reference might be improved, addressing overhead would also be increased. > After looking through the Xalan code again, I don't think those 5 > objects mentioned earlier grow at the same rate and so my suggestions > would not work . There's a core set which are maintained in parallel (the basic document tree structure), then others which are used as needed to support the data content of the document; the latter are pointed to from the core set rather than being based from the same node index.
