[OPEN-ILS-GENERAL] unAPI from getAttribute in WWW/SuperCat.pm?

Hello John,

This part of the code is pulling data from the unapi.bre() function in the
DB, so in this case, you want 'copy_id', i.e.:

f => $copy->getAttribute('copy_id'),

This said, I think we'd all be interested to know exactly what you are
trying to accomplish, as there are other existing APIs for getting copy
IDs, so I am not sure if adding it into this SRU function is the easiest
way to go.
