   NOTE: This use case also checks for varying numbers of written planes.
         Dataset A contains the full number of planes and each successive
         dataset contains one fewer plane, down to the last dataset, which
         contains zero planes. Each dataset is set to have an (unlimited
         dimension) extent equal to the number of planes written, so the
         "empty" regions will contain the VDS fill value.
