Well, there are a *lot* of fields that are repeatable and where you might well
want to display and search on all repeats for a record.  Off the top of my
head:

- EAN/UPCs, as mentioned by Mathieu
- arbitrary record identifiers (e.g., from the MARC21 035 field)
- chapter and part titles
- languages of the work
