[cddlm] CDL and namespaces

[Steve Loughran]

As implement extends, I find tests failing and have to decide if they 
are real failures or not. Here is my current one.

<?xml version="1.0"?>
<cdl:cdl 
xmlns:cdl="http://www.gridforum.org/namespaces/2005/02/cddlm/CDL-1.0"
   xmlns="http://example.org/webapps" >
   <cdl:configuration>
     <server>
       <port>8080</port>
       <security>true</security>
       <webapps/>
     </server>

   </cdl:configuration>
   <cdl:system>

     <tomcat cdl:extends="server">
       <basedir>
       </basedir>
     </tomcat>
   </cdl:system>
</cdl:cdl>

This file fails to resolve extends="server" because the 
xmlns="http://example.org/webapps" declaration puts the     server 
declaration into that ns.

My extends lookup logic assumes that any localname without a namespace 
is in the empty namepace.

Question is, is that the right assumption?

The other, perfectly valid one, would be to say that any localname in an 
extends declaration is in the same namespace as the element that is 
being extended. To get something in the empty namespace, I'd have to say 
extends=":something".

I dont see anything in the spec which covers this issue, so will file 
this as an issue on ggf.org.
