docs: Specifies that extra repeated field elements for these explicitly specified top-level field
  numbers should be ignored. Sub-fields must be specified explicitly (via {@link
  FieldDescriptor}) 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.
