// of the policies attached to groups that the user is a member of.
//
// You can optionally include a list of one or more additional policies, specified
// as strings. If you want to include only a list of policies by string, use
// GetContextKeysForCustomPolicy instead.
//
// Note: This API discloses information about the permissions granted to other
// users. If you do not want users to see other user's permissions, then consider
// allowing them to use GetContextKeysForCustomPolicy instead.
//
// 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 in an IAM policy. Use GetContextKeysForPrincipalPolicy
// to understand what key names and values you must supply when you call SimulatePrincipalPolicy.
