DOCBOOK-APPS: Help with a small customization at <ulink> on HTMLstylesheets.

Hi!

I'm trying to add a 'target' attribute to element ulink in HTML
stylesheets. Norm's originals are as follow:

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

And my customization is:

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

But, with that, I get the following error message (once for each
occorrence of <ulink>):

/usr/bin/openjade:/usr/share/sgml/conectiva-dbk-sgml/3.0/supdesenv/supdesenv-html.dsl:181:13:E: invalid value for "attributes" characteristic

Line 181 is the one with 'attributes:'... Any hint? 

I'd also have some clue on how to default to '_top' if the target
attribute isn't defined.

Thanks!
