	// SASL contains authentication related configuration.
	SASL struct {
		// Mechanisms contains enabled SASL mechanisms.
		Mechanisms []string `fig:"mechanisms" default:"[scram_sha_1, scram_sha_256, scram_sha_512, scram_sha3_512]"`

		External struct {
			Address  string `fig:"address"`
			IsSecure bool   `fig:"is_secure"`
		} `fig:"external"`
	} `fig:"sasl"`

	// CompressionLevel is the compression level that may be applied to the stream.
	// Valid values are 'default', 'best', 'speed' and 'no_compression'.
	CompressionLevel string `fig:"compression_level" default:"default"`

	// ResourceConflict defines the which rule should be applied in a resource conflict is detected.
	// Valid values are `override`, `disallow` and `terminate_old`.
	ResourceConflict string `fig:"resource_conflict" default:"terminate_old"`

	// MaxStanzaSize is the maximum size a listener incoming stanza may have.
