// When you create an extension or configure an Amazon Web Services authored
// extension, you associate the extension with an AppConfig application,
// environment, or configuration profile. For example, you can choose to run the
// AppConfig deployment events to Amazon SNS Amazon Web Services authored extension
// and receive notifications on an Amazon SNS topic anytime a configuration
// deployment is started for a specific application. Defining which extension to
// associate with an AppConfig resource is called an extension association. An
// extension association is a specified relationship between an extension and an
// AppConfig resource, such as an application or a configuration profile. For more
// information about extensions and associations, see Working with AppConfig
// extensions (https://docs.aws.amazon.com/appconfig/latest/userguide/working-with-appconfig-extensions.html)
// in the AppConfig User Guide.
