Ah. Forgive me replying to my own post -
Just read further into the DOM 2 Traversal spec,
(From section 1.2 Formal Interface Definition)
SHOW_ATTRIBUTE
Show Attr nodes. This is meaningful only when creating an iterator or
tree-walker with an attribute node as its root; in this case, it means that
the attribute node will appear in the first position of the iteration or
traversal. Since attributes are never children of other nodes, they do not
appear when traversing over the document tree.
So, it was my stupid. Looks like I'll have to rewrite the loop for the
iterator to do special things for attributes.
Thanks,
Richard.
