=head1 MODIFIERS
MapDrivenMARCXMLProc implements the following modifiers, and passes
tags => [
{
tag => tag_id,
- multi => { (tag_id . sub_code) => [ val1, val2, ... ] },
+ multi => { code => [ val1, val2, ... ] },
uni => { code => value, code2 => value2, ... },
},
...
two more hashrefs, C<multi> and C<uni>.
The C<multi> hash holds the extracted data for tag/sub mappings which
-have the C<multiple> modifier on them. The keys in C<multi> are
-composed of the tag id and subfield code, catenated
-(e.g. C<901c>). The values are arrayrefs containing the content of all
+have the C<multiple> modifier on them. The keys in C<multi> subfield
+codes. The values are arrayrefs containing the content of all
instances of that subfield in that instance of that tag. If no tags
are defined as C<multi>, it will be C<undef>.
