-- Gets a list of all of the context keys referenced in the input policies. The policies are supplied as a list of one or more strings. To get the context keys from policies associated with an IAM user, group, or role, use 'GetContextKeysForPrincipalPolicy' .
--
--
-- Context keys are variables maintained by AWS and its services that provide details about the context of an API query request. Context keys can be evaluated by testing against a value specified in an IAM policy. Use @GetContextKeysForCustomPolicy@ to understand what key names and values you must supply when you call 'SimulateCustomPolicy' . Note that all parameters are shown in unencoded form here for clarity but must be URL encoded to be included as a part of a real HTML request.
