So, what is the correct data for a citation ?

   [ANSI.T1.276-200x]
              American National Standards Institute (ANSI),
              "T1.276-200x: Draft proposed American National Standard
                         ^ s/x/3/
			    ^^^^^^^^^^^^^^^ s/Draft proposed//
              for Telecommunications Operations, Administration,
              Maintenance, and Provisioning Security Requirements for
              the Public Telecommunications Network: A Baseline of
              Security Requirements for the Management Plane", April
                                                               ^^^^^
							       s/April/?/
              2003.

And do you know what the IETF stance is on citing non-freely-available
standards work?

Thanks,
