+    When declaring beans in this file you must either use name="struts" or don't name the bean at all.
+
+    The name="struts" must be used when alias was defined in {@link org.apache.struts2.config.BeanSelectionProvider} -
+    it is then the default bean's name and {@link org.apache.struts2.config.BeanSelectionProvider} links name "struts"
+    with "default" (aliasing it)
+
+    If name won't be defined then the "default" value will be used {@link com.opensymphony.xwork2.inject.Container#DEFAULT_NAME}
+    and {@link com.opensymphony.xwork2.inject.Inject}
