Enabling the use of GRDDL with NewsML 2

I think that the first thing we should do is allow the use of the 
GRDDL "transformation" attribute on our root elements.  We need to 
do this for two reasons:

1.  Our namespace URIs are currently URNs, so one can't find a 
    GRDDL transform by following them.

2.  Even if/when we change the above, we will need to allow 
    providers to specify GRDDL transforms which can cope with 
    proprietary extensions.

So, looking at:
  http://www.w3.org/2004/01/rdxh/spec#grddl-xml
we need to add the GRDDL "transformation" attribute.  Take, for 
example, the package sample at:
  http://www.iptc.org/NAR/1.0/examples/tutorials/Example-Package.xml

We can change the initial:

  <pkg:item 
    schema="0.6" 
    guid="urn:newsml:iptc.org:20060112:package1" 
    version="4" 
    xmlns:pkg="urn:iptc:std:package:1.0:xmlns" 
    xmlns="urn:iptc:std:newsml:2.0:xmlns"
  >

to:

  <pkg:item 
    schema="0.6" 
    guid="urn:newsml:iptc.org:20060112:package1" 
    version="4" 
    xmlns:pkg="urn:iptc:std:package:1.0:xmlns" 
    xmlns="urn:iptc:std:newsml:2.0:xmlns"
+   xmlns:data-view="http://www.w3.org/2003/g/data-view#"
+   data-view:transformation=
+     "http://www.iptc.org/NAR/1.0/contributions/NewsML2-N3_3.xsl"
  >

The added lines are marked with "+".

I imagine that the example and the transform are currently not in 
synch, but we can fix that before long.
