It looks like it could be done in two ways. The $0 is supposed to
contain a parenthesized prefix containing the code of the institution
that assigned the authority record ID, and that presumably could be
used as a proxy for identifying the name or uniform title authority
file being used. For subject headings, the 6XX second indicator and
subfield $2 would identify the thesaurus, and by implication the
subject authority file that $0 would refer to.
