 *  1) One ADS record applicable to all consequent MDS records until replaced
 *     by another ADS record, i.e., last MDS records does no need to be
 *     followed by an ADS record.
 *
 *  2) Two ADS records applicable to all MDS records between them
 *     (e.g., tiepoints ADS), i.e., last MDS record should be followed
 *     by an ADS record having the same or later time-stamp.
 *
 *  The type of the ADS affects the way how the ADS records corresponding
 *  to a set of MDS records should be selected.
