In case when both relator code $4 and relator term $e are used in a record, display the relator term instead of the code. Example: 700 1 _aKuczaj, Stan A. _eHrsg. _4edt _916185026 Without relator terms being set up as an authorized value, this will display in OPAC as: Kuczaj, Stan A. [edt] If we had a rule to display $e if it is set in the record, it would be: Kuczaj, Stan A. [Hrsg.]
Bug 35981 is about adding relator codes as authorized values.
