=item Chained
Has to be specified for every child in the chain. Possible values are
-absolute and relative private action paths, with the relatives pointing
-to the current controller, or a single slash C</> to tell Catalyst that
-this is the root of a chain. The attribute C<:Chained> without arguments
-also defaults to the C</> behavior.
+absolute and relative private action paths or a single slash C</> to

+C<:Chained> without arguments also defaults to the C</> behavior.
+Relative action paths may use C<../> to refer to actions in parent
+controllers.
Because you can specify an absolute path to the parent action, it
doesn't matter to Catalyst where that parent is located. So, if your
C</foo/bar>. That action chains directly to C</>, so the C</bar/*/baz/*>
chain comes out as the end product.
+=item ChainedParent
+
+Chains an action to another action with the same name in the parent
+controller. For Example:
+
+ # in MyApp::Controller::Foo
+ sub bar : Chained CaptureArgs(1) { ... }
+
+ # in MyApp::Controller::Foo::Moo
+ sub bar : ChainedParent Args(1) { ... }
+
+This builds a chain like C</bar/*/bar/*>.
