/**
 * Meta-annotation used to indicate that an annotation provides extension support for an
 * endpoint. Extensions allow additional technology specific {@link Operation operations}
 * to be added to an existing endpoint. For example, a web extension may offer variations
 * of a read operation operation to support filtering based on a query parameter.
 * <p>
 * Extension annotations must provide an {@link EndpointFilter} to restrict when the
 * extension applies. The {@code endpoint} attribute is usually re-declared using
 * {@link AliasFor @AliasFor}. For example: <pre class="code">
 * &#64;EndpointExtension(filter = WebEndpointFilter.class)
 * public &#64;interface EndpointWebExtension {
 *
 *   &#64;AliasFor(annotation = EndpointExtension.class, attribute = "endpoint")
 *   Class<?> endpoint();
 *
 * }
 * </pre>
