We use the attributes: to generate the attributes of an element A in the
following way :

(element MY_TAG
    (make element gi: "A"
      attributes: (list (list "HREF" 
           (string-append "#" (attribute-string "REFID"))))
                 (literal "»")))
or 

(make element gi: "A"
        attributes:
          (list
            (list "NAME" (string-append "TOC" (section-id
(current-node))))
            (list "TITLE" "To document")
            (list "HREF" (string-append "#BODY" (section-id
                                                       (current-node)))))
        (make sequence 
               (literal 
                (format-number-list 
                 (hierarchical-number-recursive "D" ) "1" ".")
                " ")
               (process-children-trim))))

We use this to build TOCs with bidirectionnal links.
Could this help you ?
