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