This seems to be inventing a new namespace-management mechanism.  I'm  
always a bit nervous about schemes which require someone to maintain  
a registry of namespaces.  Was there really a problem with the old  
system of using the XML document's namespace map to scope property  

The one thing I saw missing from the old spec was a mechanism for  
doing namespace-scoped property queries.  I guess shoehorning this  
into an application/x-www-form-urlencoded query isn't ideal, but it  
could be done.  How about
