I am not wild about the idea of using a child <reference/> element. Do I
assume that this <reference/> element applies to the smallest containing
element? Then I suppose I would have to write an xpath expression to
find it.

To me that seems rather messy and contrary to the spirit of XML.  You
wouldn't mark a word as emphasized by <w><hi/>emphasized</w> -- the
normal approach would be <hi>emphasized</hi>.
The messiness arises from those Xpath expressions that would be required
for finding the commentary on Matt.1.13, etc. -- the search is not as
straightforward. You can't search for the element with
annotateWork="Matt.1.13" and annotateType="commentary".
