I think that this is correct:

-  The RDDL architecture places the RDDL document at the namespace 
   location.  This document specifies any number of links to typed 

-  The GRDDL architecture provides a few hardwired locations for the 
   transforms.  One of these locations is a specialised attribute in 
   the namespace document.

These strike me as very different approaches.  The former is open-
ended, the latter is not.

The newsml-2 list has the same spam-avoidance policy as the (set of)
public W3C lists, namely you need to be a member of the newsml-2
list in order to post to it*.  Anyone can go to:
and click on the "Join" button.

* In the case of the W3C public lists, one needs to be a member of
at least one W3C list.
