Works perfectly. My final version now looks like this: ;; usage for an XSL-like idref-set attribute 'refs' ;; (and a meaningful mode for the reference-list, e.g. bulleted list) (with-mode result-reference (process-node-list (ref-node-list (attribute-string "refs")))) ;; ref-node-list function from Norman Walsh ;; needs three functions from docbook's dblib.dsl ;; (define (ref-node-list references) (let loop ((idstrlist (split references)) (targets (empty-node-list))) (if (null? idstrlist) targets (loop (cdr idstrlist) (node-list targets (element-with-id (car idstrlist))) )))) DSSSList info and archive: http://www.mulberrytech.com/dsssl/dssslist
