  [XQuery Update Newbie] Rename all element
	nodes(in no namespace) to the same name
Hi Michael,

Here is the XQuery Update file I used:
---------------------------------------------------
for $i in doc('FitnessCenter.xml')//*
    return rename node $i as QName('http://www.gym.com', concat('gym:', local-name($i)))
---------------------------------------------------

Here is FitnessCenter.xml:
---------------------------------------------------
<FitnessCenter>
    <Member Level="platinum">
        <Name>Jeff</Name>
        <FavoriteColor>lightgrey</FavoriteColor>
    </Member>
    <Member Level="gold">
        <Name>David</Name>
        <FavoriteColor>lightblue</FavoriteColor>
    </Member>
    <Member Level="platinum">
        <Name>Roger</Name>
        <FavoriteColor>lightyellow</FavoriteColor>
    </Member>
</FitnessCenter>
---------------------------------------------------

Here is the result:
---------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<gym:FitnessCenter xmlns:gym="http://www.gym.com">
    
    <gym:Member xmlns:gym="http://www.gym.com" xmlns:gym="http://www.gym.com" Level="platinum">
        
        <gym:Name xmlns:gym="http://www.gym.com" xmlns:gym="http://www.gym.com">Jeff</gym:Name>
        
        <gym:FavoriteColor xmlns:gym="http://www.gym.com" xmlns:gym="http://www.gym.com">lightgrey</gym:FavoriteColor>
    
    </gym:Member>
    
    <gym:Member xmlns:gym="http://www.gym.com" xmlns:gym="http://www.gym.com" Level="gold">
        
        <gym:Name xmlns:gym="http://www.gym.com" xmlns:gym="http://www.gym.com">David</gym:Name>
        
        <gym:FavoriteColor xmlns:gym="http://www.gym.com" xmlns:gym="http://www.gym.com">lightblue</gym:FavoriteColor>
    
    </gym:Member>
    
    <gym:Member xmlns:gym="http://www.gym.com" xmlns:gym="http://www.gym.com" Level="platinum">
        
        <gym:Name xmlns:gym="http://www.gym.com" xmlns:gym="http://www.gym.com">Roger</gym:Name>
        
        <gym:FavoriteColor xmlns:gym="http://www.gym.com" xmlns:gym="http://www.gym.com">lightyellow</gym:FavoriteColor>
    
    </gym:Member>
</gym:FitnessCenter>
---------------------------------------------------

I am using Saxon, version 9.2.0.6

Here's how I invoked Saxon:
---------------------------------------------------
java -classpath %CLASSPATH% net.sf.saxon.Query -update:on -tree:linked -backup:on  FitnessCenter.xu
---------------------------------------------------

Roger, I have managed to reproduce (and fix) the cases where you were
getting an error about a spurious namespace conflict. But I haven't been
able to reproduce the case where you get duplicate namespace declarations in
the output.

Can you let me know exactly how you were running this to obtain this output?
