### TODO

In subsequent releases we are planning to extend this to provide things like

	var config Config

	if err := xml.NewDecoder(reader).Decode(&config); err != nil {
		return nil, err
	}

	if err := config.Validate(region, targetList); err != nil {
		return nil, err
	}

	config.SetRegion(region)
	// If xml namespace is empty, set a default value before returning.
	if config.XMLNS == "" {

		return 0, auth.ErrInvalidDuration
	}
	return dur, nil
}

// Lookup returns a new Config by merging the given K/V config
// system with environment variables.
func Lookup(kvs config.KVS) (Config, error) {
	if err := config.CheckValidKeys(config.IdentityTLSSubSys, kvs, DefaultKVS); err != nil {
		return Config{}, err
	}
	cfg := Config{}
	var err error
	v := env.Get(EnvIdentityTLSEnabled, "")
	if v == "" {
		return cfg, nil

	EnvPolicyPluginEnableHTTP2 = "MINIO_POLICY_PLUGIN_ENABLE_HTTP2"
)

// DefaultKVS - default config for Authz plugin config
var (
	DefaultKVS = config.KVS{

		config.KV{

	}
)
