Looks good to me.  I think we should include in the manual an exmaple 
that specifically suggests using a standardized value such as 
"deuterocanonical" since this is a common use, worth quasi-standardization.

If I understand your question correctly, then yes.  \xdc marks 
cross-references to deutero-canonical books.  If deutero-canonical 
material is not rendered, then neither are cross-references to that 
material.
