repeat ineffective in group arg

Bug 605150 describes this problem for DocBook XSL.

In the synop.dsl files (/html and /print versions) the repeat attribute is specified for <arg> but not for the
<arg> as a child of <group> (group arg).

I tested, and--sure enough--the repeat attribute works as expected in a naked <arg>.

I managed to correct the problem with the following addition to my customization layer:

;;==================
;; Refentry
;;==================

(element (group arg)
(let ((choice (attribute-string (normalize "choice")))
(rep (attribute-string (normalize "rep"))))
(make sequence
(if (not (first-sibling? (current-node)))
(literal %arg-or-sep%)
(empty-sosofo))
(process-children)
(cond
((equal? rep (normalize "repeat")) (literal %arg-rep-repeat-str%))
((equal? rep (normalize "norepeat")) (literal %arg-rep-norepeat-str%))
(else (literal %arg-rep-def-str%))))))

I am processing with DocBook DSSSL 1.77 via OpenJade 1.3.

The attached zip contains:

test.xml - a test refentry with repeats in an arg and in an arg within a group.

test1.html - test.xml processed without the customization

test2.html - test.xml processed with the customization
