// UpdateXssMatchSetRequest returns a request value for making API operation for
// AWS WAF.
//
// Inserts or deletes XssMatchTuple objects (filters) in an XssMatchSet. For
// each XssMatchTuple object, you specify the following values:
//
//    * Action: Whether to insert the object into or delete the object from
//    the array. To change an XssMatchTuple, you delete the existing object
//    and add a new one.
//
//    * FieldToMatch: The part of web requests that you want AWS WAF to inspect
//    and, if you want AWS WAF to inspect a header or custom query parameter,
//    the name of the header or parameter.
//
//    * TextTransformation: Which text transformation, if any, to perform on
//    the web request before inspecting the request for cross-site scripting
//    attacks. You can only specify a single type of TextTransformation.
//
// You use XssMatchSet objects to specify which CloudFront requests that you
// want to allow, block, or count. For example, if you're receiving requests
// that contain cross-site scripting attacks in the request body and you want
// to block the requests, you can create an XssMatchSet with the applicable
// settings, and then configure AWS WAF to block the requests.
//
// To create and configure an XssMatchSet, perform the following steps:
//
// Submit a CreateXssMatchSet request.
//
// Use GetChangeToken to get the change token that you provide in the ChangeToken
// parameter of an UpdateIPSet request.
//
// Submit an UpdateXssMatchSet request to specify the parts of web requests
// that you want AWS WAF to inspect for cross-site scripting attacks.
//
// For more information about how to use the AWS WAF API to allow or block HTTP
// requests, see the AWS WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/).
