>From J.Clark's example:

(define (copy-attributes #!optional (nd (current-node)))
  (let loop ((atts (named-node-list-names (attributes nd))))
    (if (null? atts)
        (let* ((name (car atts))
               (value (attribute-string name nd)))
          (if value
              (cons (list name value)
                    (loop (cdr atts)))
              (loop (cdr atts)))))))

(define (pass-throgh #!optional (nd (current-node)))
  (make element
	gi: (gi nd)
	attributes: (copy-attributes nd)))

Also you can simplify part of your stylesheet

specifying default rule

(default (pass-throgh))

which will be applied to all elements for which
explicit rules are not specified.
