[xsl] copying namespaces question

Hi all,

I have a working implementation for the use case below where I need to split
an xml file into chunks.  Although it works I'm not extremely satisfied by
hardcoding the namespace http://www.mycompany.com in my result tree.   Just
checking if this can be improved.  PS. The example is made up and simplified
but showing exactly what's needed.

Kind regards,
Robby Pelssers

<objects

  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  creationDateTime="2012-06-21T10:00:10+02:00"
  transLanguage="EN"
  baseLanguage="EN"
  messageID="1340265610203998445">

    <parent xsi:nil="true"/>
  </object>
</objects>

Expected output: 2 files called PH3330L.xml and BUK9MNP-100.xml
