Created attachment 52501 [details] Illustration of the difference between XSLT and non-XSLT subject links Version: 3.22.04.000 Also tested on older versions and 16.05.00.000 (Catalyst demo site) Using the non-XSLT detail display, subject links are broken up into increasingly detailed subdivisions that can be clicked on. In the attached image, you can see in the first three screen captures that each subject subdivision is a separate link, and creates a search at that level of the subject. It also conveniently provides a tooltip that shows which MARC subfield the subdivision is coming from. The fourth screen capture shows what happens when the XSLT display is in effect. The entire subject with all subfields are treated as a single search. The subfields cannot be searched separately. Note the the same behavior applies to the links for additional authors. It would be great to have the XSLT option work the same way as the non-XSLT option. Settings for screen capture 4 (in attachment) OPACXSLTDetailsDisplay = default TraceSubjectSubdivisions = Include Settings for screen capture 1-3 (in attachment) OPACXSLTDetailsDisplay = (empty, no XSLT) TraceSubjectSubdivisions = Include
