Q: What about a notice for diplomatic immunity, is that
something that is done on the public notice or the
security agreement?

A: What follows may sound convoluted but I think you
are up to it:

Let me put it this way, The intention of this
particular public notice is to lay claim on the use of
the name and to use it as tool to discourage another
parties use of it - unless they are willing to pay the
price as is so stipulated within what is a self-
executing contract. So let me ask you does the aspect
of diplomatic immunity enter into this particular
public notice - granted it is related but would not
introducing it within the same document be mixing
apples and oranges so to speak?

Having said that if you wish to modify the document or
add anything to it I am willing to accommodate you as
the intention here in is for me to act strictly as your
instrument.

In my humble opinion sovereign immunity is established
by going through this initial process and then building
upon it. Once this bit is complete you have the ability
to control the legal entity as its administrator ( on
the basis of your contract with it) and also use its
stuff while keeping your separation from it. 

The only caveat I would add do not abandon it entirely unless
you have something else to replace it first. For
example it is fine to turn in your driver's license but
if you have nothing to replace it that can be very
inconvenient. In that case you would want to have the
equilivant of diplomatic papers that are recognized and
also diplomatic plates. It is conceivable that you can
use these papers generated by this process to be
formally recognized as a foreign traveler but this is
not necessarily a straight forward process and there
may other solutions out there you may leverage such as
becoming adopted with another sovereign nation such as
an Indian tribe who have already done all the
preliminary work.
