+ * Returns a configuration tree for the purpose of reading configuration
directly from the underlying storage. Actual reading is only
+ * happening while invoking {@link ConfigurationTree#value()}. It will
either throw {@link NoSuchElementException},
+ * {@link StorageException} or return the value.
+ * <p/>
+ * It is important to understand how it processes named list elements.
Imagine having element named {@code a} with internalId
+ * {@code aId}.
+ * <pre><code>
+ * var namedListProxy = directProxy(namedList);
+ *
+ * // Creates another proxy.
+ * var aElementProxy = namedListProxy.get("a");
+ *
+ * // This operation performs actual reading. It'll throw an exception
if element named "a" doesn't exist anymore.
+ * // It's been renamed or deleted.
+ * var aElement = aElementProxy.value();
+ *
+ * // Creates another proxy.
+ * var aIdElementProxy = getByInternalId(namedListProxy, aId);
+ *
+ * // This operation performs actual reading as previously stated.
But, unlake the access by name, it won't throw an exception in
