[osis-core] schema 1.1_003 bug

Well, I guess missed that question. I think that would make sense
as long as there were some optional element in the <work> element
to specify a reference system.  E.g.

<works>
  <work osisWork="conf">
    <refSystem>augustine_confessions.pusey</refSystem>
  </work>
</works>

At any rate, there should be a way of tying an internal identifier
such as "conf" to an elsewhere-defined reference system such
as augustine_confessions.pusey
