+We are using I<magic> which detect repeatable fields only from
+sequence of field/subfield data generated by normalization.
+
+Repeatable field is created if there is second occurence of same subfield or
+if any of indicators are different. This is sane for most cases except for
+non-repeatable fields with repeatable subfields.

+B<TODO>: implement exceptions to magic
