Well, since one man's Mede is another man's Persian, I guess you can make 
that distinction, although I'm not sure why you would.  In your example, 
since AACR2 doesn't try to put restrictions on a note, I think foo.noteText 
is equivalent to marc.500a.  All you are really distinguishing is which 
logical index you are referencing.

(disclaimer: I know there are other cataloging rules, besides AACR2)
