--
-- * 'lscsNextMarker' - If you specify a value for @Limit@ and you have more @SizeConstraintSets@ than the value of @Limit@ , AWS WAF returns a @NextMarker@ value in the response that allows you to list another group of @SizeConstraintSets@ . For the second and subsequent @ListSizeConstraintSets@ requests, specify the value of @NextMarker@ from the previous response to get information about another batch of @SizeConstraintSets@ .
--
-- * 'lscsLimit' - Specifies the number of @SizeConstraintSet@ objects that you want AWS WAF to return for this request. If you have more @SizeConstraintSets@ objects than the number you specify for @Limit@ , the response includes a @NextMarker@ value that you can use to get another batch of @SizeConstraintSet@ objects.
