mod-copycat provides the copycat-profile schema, which includes a field called targetOptions. This field's value is an object (i.e. a set of key=value pairs). The "Z39.50 target profiles" settings page provides a way to maintain copycat profiles, but at present omits the targetOptions field because there is not presently a good way to handle this data-type (i.e. no stripes-components form control of the appropriate type).
An appropriate maintenance UI is provided by the <ControlledVocab> component in stripes-smart-components, but at present that is tied to specific physical representations of the data it maintains. Once that has been generalized (
STSMACOM-491) I should be able to use it to provide targetOptions support.
