51 C4::XSLT - Functions for displaying XSLT-generated content
55 =head2 XSLTParse4Display
57 Returns xml for biblionumber and requested XSLT transformation.
58 Returns undef if the transform fails.
60 Used in OPAC results and detail, intranet results and detail, list display.
61 (Depending on the settings of your XSLT preferences.)
