That's the problem. When target isn't specified, you get a list that
contains a non-string and that's not legal in attributes:

(I assume you modified the DTD to allow the target attribute on
ulink?)

Try something like this:

(element ulink 
  (make element gi: "A"
	attributes: (list
		     (list "HREF" (attribute-string (normalize "url")))
		     (list "TARGET" (if (attribute-string (normalize "target"))
                                        (attribute-string (normalize "target"))
                                        "_top")))
        (if (node-list-empty? (children (current-node)))
            (literal (attribute-string (normalize "url")))
            (process-children))))

                                        Be seeing you,
                                          norm
