I'm not sure about having a separate edition name and reference system
identifier.  Would we ever have an NIV using the LXX reference
system?

The full stop-delimited syntax becomes unnecessary if the work is 
described adequately in the <work> element and the osisWork attribute
is merely an opaque internal identifier (short-form work name).
