The experimental DSSSL extensions in recent versions of Jade (requires "-2" on the Jade command line) includes or-element construction rules: (or-element (MRCB100-c MRCB100-d MRCB100-e) (sosofo-append (literal " ") (process-children) ) ) (Note that sososfo-append will give a flatter flow object tree than nesting sequence flow objects, but the difference in processing time may not even be noticable.) Another option is to use a procedure: (define (add-space #!optional (children (process-children))) (sosofo-append (literal " ") children) ) ) (element MRCB100-c (add-space) ) Yet another option, especially if you have a lot of sibling elements that all get the same treatment, is to process the elements in a separate mode specified in the element construction rule of the parent element of the siblings: (element MRCB100 (with-mode add-space (process-children))) (mode add-space (default (add-space))) It's tempting to try: (element MRCB100 (sosofo-append (node-list-map 'add-space (children (current-node))))) but the procedure in node-list-map has to return a node-list, not a sosofo.
