-=head2 get_all_authorities_iterator
+=head3 controlled_indicators
+
+ Some authority types control the indicators of some corresponding
+ biblio fields (especially in MARC21).
+ For example, if you have a PERSO_NAME authority (report tag 100), the
+ first indicator of biblio field 600 directly comes from the authority,
+ and the second indicator depends on thesaurus settings in the authority
+ record. Use this method to obtain such controlled values. In this example
+ you should pass 600 in the biblio_tag parameter.
+
+ my $result = $self->controlled_indicators({
+ record => $auth_marc, biblio_tag => $bib_tag
+ });
+ my $ind1 = $result->{ind1};
+ my $ind2 = $result->{ind2};
+ my $subfield_2 = $result->{sub2}; # Optional subfield 2 when ind==7
+
+ If an indicator is not controlled, the result hash does not contain a key
+ for its value. (Same for the sub2 key for an optional subfield $2.)
+
+ Note: The record parameter is a temporary bypass in order to prevent
+ needless conversion of $self->marcxml.
