# ExtensibleBase

This class is meant to be used by AWS AppConfig resources (application, configuration profile, environment) directly.

There is currently no use
for this class outside of the AWS AppConfig construct implementation. It is
intended to be used with the resources since there is currently no way to
inherit from two classes (at least within JSII constraints).
