Hi Bryan
(BTW thanks Bob for jumping in and helping out).
Just out of interest, what kind of custom-in-memory tree have you got? Would
it be worth deriving from AbstractElement or DefaultElement and adapting to
your tree, making your tree appear as child elements and attributes?
When most trees are mapped to XML then usually, Element, Attribute and Text
nodes are the important bits to worry about, the other stuff is less
important (CDATA, DocType, Entity, ProcessingInstruction etc.)
