>  If you create a namespace with axiom_attribute_create() and then create two
> sibling elements using axiom_element_create(), passing them both the attribute pointer,
> then both elements add the attribute pointer to their internal attribute hash,
> because neither finds declated it in any of the ancerstor elements.
> Then when you call axiom_node_free_tree(), you get a segfault when axiom_element_free()
runs
> for the second element, because it calls axiom_attribute_free() on a attribute that
> the first element already freed. Both elements treat the attribute as if it was private
to
> themselves and add it to their internal attribute hashes, and then both try to free it.
