   * ``bool IndentBraces`` Indent the wrapped braces themselves.
 
-  * ``bool SplitEmptyFunctionBody`` If ``false``, empty function body can be put on a single line.
+  * ``bool SplitEmptyFunction`` If ``false``, empty function body can be put on a single line.
     This option is used only if the opening brace of the function has
     already been wrapped, i.e. the `AfterFunction` brace wrapping mode is
     set, and the function could/should not be put on a single line (as per

       {}              {
                       }
 
+  * ``bool SplitEmptyRecord`` If ``false``, empty record (e.g. class, struct or union) body
+    can be put on a single line. This option is used only if the opening
+    brace of the record has already been wrapped, i.e. the `AfterClass`
+    (for classes) brace wrapping mode is set.
 
+    .. code-block:: c++
+
+      class Foo   vs.  class Foo
+      {}               {
+                       }
+
+  * ``bool SplitEmptyNamespace`` If ``false``, empty namespace body can be put on a single line.
+    This option is used only if the opening brace of the namespace has
+    already been wrapped, i.e. the `AfterNamespace` brace wrapping mode is
+    set.
+
+    .. code-block:: c++
+
+      namespace Foo   vs.  namespace Foo
+      {}                   {
+                           }
