I have reviewed the conditions you have set upon the PRM for changes that
must be made prior to an Agency Review.  I have the following proposals
for addressing your conditions.  (NOTE:  Peter's conditions require a much
more comprehensive response and I am unable to perform them myself... I
have referred Peter's comments to the lead editor).

Erik(1): Due to the way in which the NDM/XML integrated schema is
constructed, I think the namespace header you cite is actually correct.
The master schema referred to imports the required namespace.  Thus I
don't think a change to the existing text is required.  I do agree that
the structure of the NDM/XML integrated schema should be addressed; I
think this structure has complicated and delayed my ability to respond to
John Pietras' concerns about multiple schemas in the same namespace with
the same "oemType".

Erik(2):  I would say that it's a challenge keeping up with the policy
changes "in progress" with the SANA and its registries. In particular, I
have looked at the "Organization" registry that you cite and it is not
nearly complete enough for Navigation WG needs (e.g., "JSpOC" is the major
producer of CDM instantiations and OMM instantiations, the Space Data
Center (SDC) also creates CDMs).  The abbreviation set seems incomplete as
well... is "MSFC" enough? Why isn't "NASA/MSFC" included? Is "ESA" enough?
 CDMs are planned for production by "ESA_ESAC", and OEMs are produced by
"ESOC". I don't feel it is possible to refer to this "organization"
registry in a CCSDS Red Book until it is an "approved" registry; right now
it is still a "candidate". What are the plans for "completing" this
registry and moving it to approved status?  Nonetheless, I will provide
some text for Tom to apply to the SANA annex.

Erik(3): Maybe there should be a simple, standard registration rule that
all registry change proposals are submitted to the SANA Operator, who will
determine who will act upon them. Then if the WG still exists, the SANA
refers the proposal to the WG Chair; if the WG does not still exist, the
SANA sends the proposal to the applicable AD; if the Area no longer
exists, the SANA sends the proposal to the CESG. Then everyone can have
change proposals to any registry arbitrated by the SANA (can we assume it
has persistence?). I will supply a new registration rule for Tom to apply
to the Agency Review copy that indicates change requests should be
submitted to sanaregistry.org.   (Aside:  given what you say about WG's
not being standing bodies within the CCSDS, which I do acknowledge, it is
a bit puzzling that the CESG Chair has requested WG Chairs to put "Draft
Projects" into the project framework
px), and also update 5 year plans at each Plenary... these provide an
excellent vehicle for perpetuating a WG.  But OK...).
