docs: Check that options have the correct arguments.
  <p>
  This method is not required, but is recommended,
  as every option will be considered valid if this method
  is not present.  It will default gracefully (to true)
  if absent.
  <p>
  Printing option related error messages (using the provided
  DocErrorReporter) is the responsibility of this method.
  
  @return true if the options are valid.
