I believe this is not a bug, because of assumptions by sxml.  sxml
does not appear to allow any sharing of structure, if I'm reading the
specification correctly:


The sentence: "Every child is unique; items never share their children
even if the latter have the identical content."

applies here.  It sounds like SXML is not DAG-like: it truly needs to
be tree-like.
