docs: Specifies that extra repeated field elements for these explicitly specified field descriptors
  should be ignored. Sub-fields must be specified explicitly if their extra elements are to be
  ignored as well.
  
  <p>Use {@link #ignoringExtraRepeatedFieldElements()} instead to ignore these for all fields.
  
  @see #ignoringExtraRepeatedFieldElements() for details.
