+===== Declaring stereotype with `@Priority`
+
+A stereotype may declare a `@Priority` annotation which functions as a means of enabling and ordering affected alternatives, interceptors, and decorators (in {cdi_full}).
+
+If a bean declares two different stereotypes that declare different priority values, the bean must explicitly declare a `@Priority` annotation. If the bean does not explicitly declare priority, the container automatically detects the problem and treats it as a definition error.
+
+If a bean explicitly declares priority, any priority values declared by stereotypes are ignored.
+
+Following sample shows a stereotype that can be used to mark bean as globally enabled alternative:
+
+[source, java]
+----
+@Alternative
+@Priority(Interceptor.Priority.APPLICATION + 5)
+@Stereotype
+@Target(TYPE)
+@Retention(RUNTIME)
