While trying to transform an xhtml document I ran into this general case:

copy $ul := 

<ul xmlns="http://www.w3.org/1999/xhtml">

<li>item</li>

<li>item</li>

</ul>

modify

(

  rename node $ul as QName("http://www.w3.org/1999/xhtml","ol"),

  insert node attribute class {"a"} into $ul

)

return $ul

which throws an "[XUDY0024] New namespaces conflict with each other." error.

After reading the XQuery update facility recomendation it wasn't clear to me if this is supposed to happen. Do I *have* to use chained copy statements to achieve both renaming a node an inserting an attribute?

Thanks, Alex
