### Custom OpenAPI *path operation* schema

The dictionary in `openapi_extra` will be deeply merged with the automatically generated OpenAPI schema for the *path operation*.

So, you could add additional data to the automatically generated schema.

// Supported status types
const (
	Enabled  Status = "Enabled"
	Disabled Status = "Disabled"
)

// DeleteMarkerReplication - whether delete markers are replicated - https://docs.aws.amazon.com/AmazonS3/latest/dev/replication-add-config.html
type DeleteMarkerReplication struct {
	Status Status `xml:"Status"` // should be set to "Disabled" by default
}

// IsEmpty returns true if DeleteMarkerReplication is not set

    val proxySelector = RecordingProxySelector()
    val socketAddress = InetSocketAddress.createUnresolved("myproxy", 8008)
    proxySelector.proxies.add(Proxy(Proxy.Type.HTTP, socketAddress))

    // Define two host names for the DNS routing of fake proxy servers
    val proxyServer1 = InetAddress.getByAddress("proxyServer1", byteArrayOf(127, 0, 0, 2))

    consuming it. This may be handy for interceptors!
 *  New: `HttpUrl.newBuilder()` resolves a link to a builder.
 *  New: Add the TLS version to the `Handshake`.
 *  New: Drop `Request.uri()` and `Request#urlString()`. Just use
    `Request.url().uri()` and `Request.url().toString()`.
 *  New: Add URL to HTTP response logging.
 *  New: Make `HttpUrl` the blessed URL method of `Request`.
