+	 * Whether or not bean definition profiles from superclasses should be
+	 * <em>inherited</em>.
+	 *
+	 * <p>The default value is <code>true</code>, which means that an annotated
+	 * class will <em>inherit</em> bean definition profiles defined by an
+	 * annotated superclass. Specifically, the bean definition profiles for an
+	 * annotated class will be appended to the list of bean definition profiles
+	 * defined by an annotated superclass. Thus, subclasses have the option of
+	 * <em>extending</em> the list of bean definition profiles.
+	 *
+	 * <p>If <code>inheritProfiles</code> is set to <code>false</code>, the bean
+	 * definition profiles for the annotated class will <em>shadow</em> and
+	 * effectively replace any bean definition profiles defined by a superclass.
+	 *
+	 * <p>In the following examples, the {@code ApplicationContext} for
+	 * {@code BaseTest} will be loaded using only the &quot;base&quot;
+	 * bean definition profile; beans defined in the &quot;extended&quot; profile
+	 * will therefore not be loaded. In contrast, the {@code ApplicationContext}
+	 * for {@code ExtendedTest} will be loaded using the &quot;base&quot;
+	 * <strong>and</strong> &quot;extended&quot; bean definition profiles.
