        <p>This operation creates a new event channel. Along with the channel
          reference an id is returned which can be used when invoking other
          operations exported by this module. The Quality of Service argument
          supplied will be inherited by objects created by the channel. For more
          information about QoS settings see the <c>User's Guide</c>.</p>
        <p>If no QoS- and/or Admin-properties are supplied (i.e. empty list),
          the <em>default</em> settings will be used. For more information, see the 
          User's Guide.</p>
