Why you don`t use 'pattern'.

      'path' => $path,
      'arguments' => array('form' => NULL),
    ),

      'arguments' => array('form' => NULL),
    ),

      'arguments' => array('content' => NULL, 'object' => array(), 'context' => NULL),
    ),
    'content_view_multiple_field' => array(
      'arguments' => array('items' => NULL, 'field' => NULL, 'data' => NULL),
    ),
    'content_multiple_values' => array(
      'arguments' => array('element' => NULL),
    ),
  );
}

If you use the 'pattern' in the subject, then do not have to put content-field.tpl.php the root of the theme, and togdalyuboy template will be perfectly located.
