--
-- 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 a '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, the name of
--     the header.
-- -   'TextTransformation': Which text transformation, if any, to perform
--     on the web request before inspecting the request for cross-site
--     scripting attacks.
--
-- You use 'XssMatchSet' objects to specify which CloudFront requests 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:
--
-- 1.  Submit a < CreateXssMatchSet> request.
-- 2.  Use < GetChangeToken> to get the change token that you provide in
--     the 'ChangeToken' parameter of an < UpdateIPSet> request.
-- 3.  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
-- <http://docs.aws.amazon.com/waf/latest/developerguide/ AWS WAF Developer Guide>.
