Jun has corrected this. My impl isnt handling it properly, because lazy 
stuff is on my todo list. It doesnt resolve it, but it doesnt generate 
that output either.

Well, it may not be copied, but its a kind of chaining. Something bad 
should happen.

My test is 'failing' with what appears to be one of the possible 
resolutions.

<system xmlns="http://www.gridforum.org/namespaces/2005/02/cddlm/CDL-1.0">
             <app xmlns="">
               <hostname cdl:ref="hostname" 
xmlns:cdl="http://www.gridforum.org/namespaces/2005/02/cddlm/CDL-1.0"/>
               <database cdl:ref="hostname" 
xmlns:cdl="http://www.gridforum.org/namespaces/2005/02/cddlm/CDL-1.0"/>
             </app>
           </system>

There is clearly a bug in my code here. as usual.
