Could one of the gurus in this area please clarify the following:

In an EN-NN registration or deletion:

 * If a X'3C' CV is present (or a X'3D', X'00F4'), must it
   contain the name of the ENCP that sent the GDS, or can
   the ENCP surrogately register for another ENCP ?
> The X'3C' must be for the ENCP that sends the Register.
> No surrogate registrations are allowed.

 * If an ENCP can be a surrogate in this fashion:

   * Can multiple X'3C' or X'3D', X'00F4' CVs be present in
     a single register/delete (with different ENCP names) ?
> Since only one value for the X'3C' is allowed, multiple
> X'3C' CVs should not be used.  In addition to being
> inefficient, I'm told there's an implementation that won't
> successfully register resources after a second X'3C'.

   * Can the ENCP include a NNCP X'3C' CV that specifies a
     NN other than the one receiving the register ? i.e.
     surrogately register for another ENCP owned by a
     different NNCP.
> The NN receiving a Register assumes it is the NNS for all
> resources.  No kind of surrogate registration is supported.
> The NNCP X'3C' is optional, but at most one should be included.

In a NN-CDS registration:

 * Can the NN register resources for multiple ENCPs in its
   domain in a single gds ?
> Sure.  Include as many as you want (subject to the GDS
> variable length limitations).

 * Can the NN surrogately register resources for other NNs ?
   If so, can multiple NNCP X'3C' CVs be present (with different
   names).
> No.  An NN may only include its own name in a X'3C' with
> resource type X'00F6', and there should only be one of
> these in the GDS variable.

I know I'm probably the only one crazy enough to think about
these scenarios, but I just wanted to clarify these points.

Thanks in advance.
