non-repeatable fields with repeatable subfields. |

166 |

This is sane for most cases. Something like: |
167 |
|
|
168 |
|
900a-1 900b-1 900c-1 |
169 |
|
900a-2 900b-2 |

|
900a-3 |
171 |
|
|
172 |
|
will be created from any combination of: |
173 |
|
|
174 |
You can change behaviour of that using C<marc_repeatable_subfield>. |
900a-1 900a-2 900a-3 900b-1 900b-2 900c-1 |
175 |
|
|
176 |
|
and following rules: |
177 |
|
|
178 |
|
marc('900','a', rec('200','a') ); |
179 |
|
marc('900','b', rec('200','b') ); |
180 |
|
marc('900','c', rec('200','c') ); |
181 |
|
|
182 |
|
which might not be what you have in mind. If you need repeatable subfield, |
183 |
|
define it using C<marc_repeatable_subfield> like this: |
