[xquery-talk] Namespace conflict ?

Christian, thank you for your lines.

When I prefix the new name, it works, even though the namespace binding is the same. 

declare namespace gym='http://www.mygym.com';

let $i:=(doc("FitnessCenter.xml")//gym:Name)[1]

return rename node $i as QName('http://www.gym.com', “gym:Name")
with
<?xml version="1.0" encoding="UTF-8"?>

<FitnessCenter xmlns="http://www.mygym.com">
  <Member Level="platinum">
      <Name>Jeff</Name>
      <FavoriteColor>lightgrey</FavoriteColor>
  </Member>
</FitnessCenter>

I cannot see the namespace conflict.
Thanks anyway
Always
Leo
