-Probably best to avoid using this ... it has some rather striking problems:
-
-=over 2
-
-* saves blank subfields
-
-* subfield order is hardcoded to always start with 'a' for repeatable tags (because it is hardcoded in the addfield routine).
-
-* only possible to specify one set of indicators for each set of tags (ie, one for all the 650s). (because they were stored in a hash with the tag as the key).
-
-* the underlying routines didn't support subfield reordering or subfield repeatability.
