Note
All requests for value assignment from the various number spaces below
require "Specification Required".  Requests must be specified in sufficient
detail so that interoperability between independent implementations is
possible.  Possible forms of documentation include, but are not limited to,
RFCs, the products of another standards body (e.g. 3GPP), or permanently
and readily available vendor design notes.
