       "the emphasis is NOT on the endpoints but on the management of "
       "the pipe itself - its state, configuration, etc. NetworkPipes "

       "\'transfer of information . . . between . . . endpoints\'. "

          "of this class. In order to ensure uniqueness within the "
          "NameSpace, the value of InstanceID SHOULD be constructed "
          "using the following \'preferred\' algorithm: \n"
          "<OrgID>:<LocalID> \n"
          "Where <OrgID> and <LocalID> are separated by a colon "

          "similar to the <Schema Name>_<Class Name> structure of "
