Allow ignored namespaces everywhere?

Now that we have a p:doc(umentation) element, does it still make sense
to have support for ignoring namespaces at every level? Do we really
have any use case for:

 <p:xslt p:ignored-prefixes="x">
   <p:input port="source">
     <x:ignore-me/>
     <p:document href="http://example.com/foo">
       <x:ignore-me-too/>
     </p:document>
   </p:input>
   <x:ignore-me-also/>
 </p:xslt>


                                        Be seeing you,
                                          norm
