What, no takers? To let you out of your misery, given the following query

declare copy-namespaces no-preserve, inherit;
<doc>
   <a>{<b xmlns:p="q"/>}</a>
   <a><b xmlns:p="q"/></a>
</doc>

The correct output, I believe, is:

<doc>
   <a>
      <b/>
   </a>
   <a>
      <b xmlns:p="q"/>
   </a>
</doc>
