Description:

When several resources implement the same interface, the service provider should be able to mark a particular implementation as Default. This resource implementation will be selected when several implementations exist and the user has not specified a preference via an environment.

Resources that are the default implementation should be designated as such in via api requests for resource types as well as in any generated documentation.
