"This introduction was fashioned as a proof of concept of the technical and
business feasibility of introducing more TLDs into the DNS. Proceeding with
an initial proof of concept was in response to the advice of ICANN's
Protocol Supporting Organization (PSO) and its Domain Name Supporting
Organization (DNSO) to proceed cautiously and in an orderly fashion. The PSO
and the DNSO represent the consensus views of the technical and the
user/business/other institutional communities, respectively."
