+/**
+ * {@code @SessionScope} is a specialization of {@link Scope @Scope} for a
+ * component whose lifecycle is bound to the current web session.
+ *
+ * <p>Specifically, {@code @SessionScope} is a <em>composed annotation</em> that
+ * acts as a shortcut for {@code @Scope("session")} with the default
+ * {@link #proxyMode} set to {@link ScopedProxyMode#TARGET_CLASS TARGET_CLASS}.
+ *
+ * <p>{@code @SessionScope} may be used as a meta-annotation to create custom
+ * composed annotations.
