This enhancement lets you modify the attributes "repeatable" and "unique identifier" for patron attribute types. Before this change it was not possible to modify these after they were initially set.
Now you can modify patron attribute types, depending on the existing values recorded:
- repeatable: can make repeatable if it wasn't before; can make not repeatable once any repeatable values are removed
- unique identifier: if unique is set you can't add the same value to other patrons; you can't make an existing attribute unique until you edit all the existing values recorded for patrons and make them unique
