That would align well with HXL. We allow the code via the +code attribute (e.g. #adm1 +code) and the name via the _+name+ attribute (e.g. #adm1 +name), optionally in multiple languages (#adm1+name+i_ar, #adm1+name+i_fr, etc). It would be good to be able to represent all of that in IATI when we start mapping back and forth.
