 =head1 METHODS
 
+Methods not listed here are delegated to the connected schema used by the model
+instance, so the following are equivalent:
+
+    $c->model('DB')->schema->my_accessor('foo');
+    # or
+    $c->model('DB')->my_accessor('foo');
+
+Methods on the model take precedence over schema methods.
