'is_close' - true, если тег всегда считается закрытым (например [hr]).
'lbr' - число переводов строк, которые следует игнорировать перед
элементом.
'rbr' - число переводов строк, которые следует игнорировать после
элемента.
'ends' - список тегов, начало которых обязательно закрывает данный.
'permission_top_level' - true, если тегу разрешено находиться в корне
дерева элементов.
'children' - список тегов, которым разрешено быть вложенными в данный.
