    description
      "Common groupings for the Query API.  These groupings
     are used by protocol-specific modules; currently one for
     NETCONF (tailf-netconf-query) and one for REST
    (tailf-rest-query).

     The Query API has four functions:  'start-query',
     'fetch-query-result', 'reset-query', and 'stop-query'.

     'start-query' is used to start a new query.  It returns
     a query handle, before the system has started to evaluate
     the query.  The query-handle is used in the other
     functions.

     'fetch-query-result' is repeatedly used to get chunks of the
     result of the query.

     'reset-query' is optionally used to restart the query, possibly
     from a new offset in the result.

     'stop-query' cleans up the resources associated with the query.

     This module defines the input and output parameters to these
     functions as groupings.  The protocol-specific modules that use
     these groupings encapsulate them in protocol-specifc operations.";
