Meaning of Single Administrative Domain

All

Perhaps someone out there can help me as I am having some difficulty in
defining the exact meaning of a single administrative domain that is
part of the last call for "Emergency Telecommunications Services (ETS)
Requirements for a Single Administrative Domain".

According to draft-ietf-ieprep-domain-req-02.txt section 1 the
explanation of the Administrative Domain: is "The collection of
resources under the control of a single administrative authority.  This
authority establishes the design and operation of a set of resources
(i.e., the network)." 

However further on in the document in section 4.2 in the explanation of
the relationship to the work ongoing in the ITU-T this statement is
made: "However, to provide a bridge of
understanding, the reader can assume that ETS within the IETF is
synonymous with TDR in the ITU -- each involving authorized use of a
service that attempts to compensate for stressed conditions of
resources."

These two statements are in my mind conflicting. In the recent ITU-T PCP
meeting one of the definitions of TDR is to do with international
communications to and from the disaster area and local communications at
the disaster area. This is not a single network on the contrary it is a
requirement for cooperation of many networks especially international
networks.

I may have misunderstood the point here and would grateful if someone
could put me on the correct path.
